Abstract

In the present study, the luminescence characteristics and the effect of conductivity on cathodoluminescene of CaTiO$_3$:Pr was studied using dick specimens sintered at various temperatures and atmosphere. As a sintering temperature was increased from 1100 to 1400 $^{\circ}C$, conductivity of CaTiO$_3$:Pr phosphor was improved and CL brightness was also increased about four times and decay times was reduced from 0.29 to 0.21 msec. And all samples prepared in Ar showed high conductivity, CL brightness and short decay time in comparison with those sintered in air.
