ZnS:Cu의 청색 발광 특성과 염료 혼합비 의존성
Blue Electroluminescent Properties and Dependent of Dye Mixed ratio of ZnS:Cu
초록
ZnS:Cu phosphor used on powder electroluminescent device has a green emission in low frequency and a blue emission in high frequency. In this paper, to obtain the powder electroluminescent device of the blue emission in low frequency, the emission properties with mixed the ratio between phosphor and dye was investigated. The mixed ratio of the dye was from 0 to 5 weight percent. To inquire into the blue emission, the emission spectrum, the CIE coordinate system and the brightness were measured.
