| Abstract: | In this paper , the relation between brightness, firing temperature of ZnS: Cu , Mn ACEL and Cu content was investigated .The PL and EL spectra of the material were also sudied .The ageing propertties was much improved by annealing and the brightness of
the of orange ZnS: Cu, Mn ACEL screen still reached more than 8 cd / m2after having excited for 1,000 hours under the excitation of 220v and 50Hz. It had met the requirments in use. |
