Preparing ZnGa_2O_4 Phosphor of Field Emission Display by Solid-State Sintering

抄録

ZnGa_2O_4 phosphor obtained from the first fired process is low luminance intensity and low efficiency. By the treatment of secondary fired process, the maximum luminance intensity and efficiency of ZnGa_2O_4 phosphor obtained by the second fired treatment process are 2050 cd/m^2 and 0.198 lm/W, respectively. The CIE chromaticity coordinate of ZnGa_2O_4 phosphor is at X=0.1696,Y=0.1608. The emission color of ZnGa_2O_4 phosphor is blue.
