Abstract:
This study examines the feasibility of using the emission material of ZnGa 2 O 4 phosphor in field emission display (FED). ZnGa 2 O 4 is a low-voltage cathodoluminescent phosphor having a spinel structure. ZnGa 2 O 4 phosphor obtained from the first fired process has low luminance intensity and low efficiency. Treating the secondary fired process can markedly enhance the crystallization and cathodoluminescent properties of ZnGa 2 O 4 phosphor. Among these improvements include a decrease in the values of full width at half maximum (FWHM) of X-ray diffraction (XRD), along with an obvious increase in the luminance intensity and efficiency of ZnGa 2 O 4 phosphor. The maximum luminance intensity and efficiency of ZnGa 2 O 4 phosphor obtained by the secondary fired treatment processes are 2050 cd/m 2 and 0.198 lm/W, respectively. In addition, the CIE chromaticity coordinate of the ZnGa 2 O 4 phosphor is X =0.1696, Y =0.1608. Moreover, the emission color is blue.
