Sol-Gel Synthesis of CaAl12O19:Mn Phosphor and Red Luminescence by Near-Ultraviolet/Blue Excitation = Sol-Gel Synthesis of CaAl12O19:Mn Phosphor and Red Luminescence by Near-Ultraviolet/Blue Excitation

다국어 초록 (Multilingual Abstract)

CaAl12O19:Mn red-emitting phosphor has been synthesized by a novel sol-gel route for the possible applications for white LEDs or white OLEDs. The sol-gel derived CaAl12O19:Mn phosphor was crystallized into a single crystalline phase and showed red luminescence excited by NUV and blue wavelength. The main red emission peak was at 653 nm with satellite peaks while the excitation bands consisted of three peaks around 334 nm, 397 nm, and 468 nm. The sol-gel derived CaAl12O19:Mn red-emitting phosphor would be compatible for the possible application of white LEDs or white OLEDs through NUV- or blue- excitation.
