(M, S)-최적인 동반수 h($h\geq2$)을 갖는 가장 균형된 계획에 관한 연구
배종성 한국통계학회 1997 응용통계연구 Vol.10 No.1
본 논문에서는 블록의 크기와 반복수가 동일한 이항계획인 경우 동반수 h($h\geq2$)을 갖는 가장 균형된 계획은 (M,S)-최적계획임을 보인다. 동반수가 3이상인 경우는 배치계획을 작성하기가 매우 힘들기 때문에 기존의 PBIBD(3)의 배치계획들 중에서 동반수 3을 갖는 가장 균형된 배치계획들만을 조사하였다. In this paper, we show that the proper equi-replicate binary designs with h($h\geq2$)-concurrence most balanced designs are (M, S)-optimal. It is very difficult to construct with more than 3-concurrence designs, so we choose 3-concurrence most balanced designs out of the known PBIBD(3).

Pulsed Laser Deposition 방법으로 증착시킨 Se가 첨가된 ZnGa2O4:Mn2+ 박막 형광체의 형광 특성
배종성,정중현,문병선,이성수 한국물리학회 2004 새물리 Vol.48 No.6
Mn-doped ZnGa$_2$O$_{4-x}$Se$_x$ thin-film phosphors were grown using pulsed laser deposition (PLD) under various growth conditions. A structural characterization was carried out on a series of ZnGa$_2$O$_{4-x}$Se$_x$ : Mn$^{2+}$ films grown on MgO (100) substrates by using Zn-rich ceramic targets. Zn-rich ceramic targets were prepared to compensate for the vaporization loss of Zn during PLD. The substrate temperature was fixed at 600 $^\circ$C and the oxygen pressure was varied from 50 to 200 mTorr. The luminescence results indicated that MgO (100) is a promising substrate for the growth of high-quality of ZnGa$_2$O$_{4-x}$Se$_x$ : Mn$^{2+}$ films. The crystallinity and the surface roughness of the ZnGa$_2$O$_{4-x}$Se$_x$ : Mn$^{2+}$ films were highly dependent on the oxygen pressure. Epitaxial films were obtained on MgO (100) substrates due to the low lattice mismatch between ZnGa$_2$O$_4$ and MgO. The crystallinity of the films was improved with Se doping. The root-mean-square surface roughness of these ZnGa$_2$O$_{4-x}$Se$_x$ : Mn$^{2+}$ films was found to initially increase from 3.25 nm at x = 0.00 to 10.92 nm at x = 0.075 then decrease to 8.43 nm at x = 0.10 as the amount of Se was increased. Incorporation of Se into the ZnGa$_2$O$_4$ lattice led to a remarkable increase into photoluminescence. The highest green emission intensity was observed with ZnGa$_2$O$_4$Se$_x$ : Mn$^{2+}$ (x = 0.075) films whose brightness was increased by a factor of 3.1 in comparison with that of ZnGa$_2$O$_4$ : Mn$^{2+}$ films. This phosphor is promising for applications in flat panel displays.

Enhanced Luminescent Characteristics of Y2−xGdxO3:Eu3+ Ceramic Phosphors by Li-Doping
배종성,심규성,문병기,Sung Boo Kim,정중현,이성수,김중환 한국물리학회 2005 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.46 No.1
The influence of lithium doping on the crystallization, the surface morphology, and the luminescent properties of Y2−xGdxO3:Eu3+ ceramic phosphors was investigated. The crystallinity, the surface morphology, and the photoluminescence (PL) of ceramics depended highly on the Li-doping and the Gd content. The relationship between the crystalline and morphological structures and the luminescent properties was studied, and Li+-doping was found to effectively enhanced not only the morphology but also the luminescent brightness of Y2−xGdxO3:Eu3+ ceramics. In particular, the incorporation of Gd into the Y2O3 lattice could induce remarkable increase in the PL. The highest emission intensity was observed with Li-doped Y1.35Gd0.60O3:Eu3+ ceramics whose brightness was increased by a factor of 1.6 in comparison with that of Li-doped Y2O3:Eu3+ ceramics.

블럭계획에서 조화행렬(concordance matrix)이 퍼뮤테이션 행렬(permutation matrix)들의 크로네커 곱(Kronecker product)의 선형결합으로 표시되면, 그러한 블럭 계획들은 특성치 C (Property C)를 갖고 특성치 C를 갖는 블럭계획들은 역행렬의 계산없이 블럭내 분석이 가능하다(Paik, 1985). $L_i$ 계획($L_i$ PBIB design)이 특성치 C에 속하는 것을 보이기 위하여, 조화행렬의 구조가 다중순환형식임을 보였다. A block design will be said to have Property C if the concordance matrix can be expressed as a linear combination of Kronecker product of permutation matrices. No matrix inversions are necessary for the intrablock analysis of the block designs which possesses the Property C(Paik, 1985). In this paper, in order to show the Li type PBIB designs possesses the Property C, we suggest the structure of the concordance matrices of Li type PBIB designs are multi-nested block circulant pattern.

배종성,박성균 한국물리학회 2011 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.59 No.4
The optical and the structural properties of Sr_2SiO_4:Eu^(3+) thin-film phosphors grown on MgO(100) were investigated using X-ray diffraction, X-ray photoelectron spectroscopy (XPS) and photoluminescence (PL) spectrometry. The thin films exhibited a high-temperature orthorhombic phase and a change of the preferred orientation from the (013) to the (121) direction as the oxygen partial pressure was increased. XPS data also revealed a variation in the O 1s chemical environment as the oxygen partial pressure increased. The PL intensity increased with increasing oxygen partial pressure and reached maximum intensity for the film grown at 150 mTorr which showed the largest surface roughness. The enhancement of the PL intensity could be related to surface roughness.

Optical and surface analysis of lithium incorporated GdVO4: Eu3+ phosphor powders
배종성,S.S. Park,T.E. Hong,J.P. Kim,J.H. Yoon,정의덕,M.S. Won,정중현 한국물리학회 2009 Current Applied Physics Vol.9 No.3
GdVO4:Eu3+ and Li-doped GdVO4:Eu3+ phosphor powders have been studied as potential red phosphors for application to flat panel display application. GdVO4:Eu3+ (the molar ratio of Eu3+ = 0.03) and corresponding Li-doped (nominal molar ratio of Li+ = 0.03) phosphors were synthesized by solid state reaction method. The influence of Li-doping on the crystallization, the surface morphology, chemical states, ion distribution and photoluminescent properties of GdVO4:Eu3+ phosphor powders were investigated. This phosphor showed photoluminescent brightness and crystallization increased when Li ions were doped. The relationship between crystalline and photoluminescent properties were also studied, i.e., Li+-doping effectively enhanced not only the crystallization but also the photoluminescent brightness of GdVO4:Eu3+ powders. Comparing to GdVO4:Eu3+, the photoluminescent brightness of Li-doped GdVO4:Eu3+ powder was increased by a factor of 2.3 times.
