RESEARCH AND INVESTIGATION OF CATHODOLUMINESCENT PHOSPHOR FILMS PREPARED BY SOLUTION SPRAYING.

摘要

The objective of the project was to determine the capabilities and necessary compromises in preparing cathodoluminescent films by a chemical solution spray process. This spray process is capable of forming cathodoluminescent films in situ on substrates which can withstand a spray temperature of 300C and a heat treatment temperature of 600C. Desired dopants may be incorporated by adding them to the spray solution. The cathodoluminescent film compositions investigated were: CdWO4, CdWO4:Sm, CdWO4:Ce, ZnWO4, Zn2SiO4:Mn,CdS:Ag,ZnS:Ag,and ZnCdS:Ag. Properties of these films were evaluated by x-ray diffraction analysis,by photo-and cathodoluminescent brightness and spectral emission,and by thermoluminescent glow-curve studies. (Author)
