The ZnGa2 O 4 Phosphor for Low‐Voltage Blue Cathodoluminescence
Source abstract
Abstract
The phosphor has been investigated for its application to vacuum fluorescent displays (VFDs) utilizing low‐voltage cathodoluminescence. It is expected that this oxide phosphor does not cause damage to filaments in VFD's, while it is a serious problem for conventional sulfide phosphors. This phosphor shows blue luminescence with a spectral peak at 470 nm and a chromaticity at and . A luminous efficiency of 0.7 lm/W has been obtained, when the VFD with this phosphor is operated at 30 V dc. The results of high‐temperature operating life test have proven the excellent stability of VFDs utilizing this phosphor.
