Design and transmittance measurement of the Ge1-xCx antireflection coatings

다국어 초록 (Multilingual Abstract)

Ge1-xCx is used as high antireflection and protection
coating on ZnS and ZnSe. Ge1-xCx coatings with a type of
design of gradient index layers can be used in very broad bands. A
technique combining medium frequency (MF) with direct-current (DC)
magnetron reactive sputtering was used to deposit Ge1-xCx
films based on our theoretical designs. The results according to
experimental measurements show that the highest transmittance of
Ge1-xCx coated on ZnSe slab can reach 94% at 8.5 μm,
to transmittance value above 80\% can be obtained within the whole
region of 5.8-12 μm and an average transmittance of 82.4% can
be obtained within the range of 2.3 -- 14 μm. The average
transmittances of ZnSe slab deposited with Ge1-xCx are 20
-- 30% higher than that of ZnSe in the corresponding band
area.
