近来,低压荧光显示的应用范围日益扩大,例如汽车上的仪表盘和收音机上的电频管都应用了荧光显示,作为图表、字符和电视的平板显示也正在发展.低压荧光显示发展的特点是逐渐走向多色化.这就要求研制不同颜色的荧光粉,而制备三基色中的红色低压荧光粉尤为迫切.(Cd_(0.8)Zn_(0.2))S:Ag是早期发展的彩色电视红粉,它与其他高压荧光粉一样;由于导电性差的原因,在低压下不能发光.镜味昭行等报道,在荧光粉中增加硫化镉的含量能增加荧光粉的导电性,但仍不能满足低压荧光粉高导电性的要求.如果在
Recently, the application of low-pressure fluorescent display has been expanding, for example, fluorescent tubes are used in dashboards and radio frequency tubes in automobiles, and flat-panel displays are being developed as charts, characters and televisions. The development of low-pressure fluorescent displays is characterized by Which requires the development of different color phosphors, and the preparation of red low-voltage phosphors in the three primary colors is particularly urgent. (Cd_ (0.8) Zn_ (0.2)) S: Ag is an early development of color TV red, It is the same as other high-voltage phosphors; due to poor conductivity, it can not emit light under low pressure. According to reports by Zhao Zhaowei, increasing the content of cadmium sulfide in phosphors can increase the conductivity of phosphors, but still can not meet the needs of low- Powder high conductivity requirements
