摘要

A series of Zn_(1-x)Mn_(x)Al_(2)O_(4) (x velence 0.001 approx 0.08) phosphors were synthesized by a traditional solid-state reaction route. Their photoluminescence under vacuum ultraviolet (VUV, energy E > 50000 cm~(-1), wavelength lambda < 200 nm) and cathodoluminescence under low-voltage electron beam excitation were evaluated. The luminescence decays were also measured. The intense green emission was observed with a peak at about 510 nm upon 172/147 nm excitation. The luminescence of optimum phosphor Zn_(0.99)Mn_(0.01)Al_(2)O_(4) (ZAM) was compared with that of commercial green phosphor Zn_(2)SiO_(4):Mn~(2+) (ZSM). The maximum emission intensity of ZAM is larger than that of ZSM under 172/147 nm and low-voltage electron beam excitation. The values of chromaticity coordinates reveal the phosphors can evidently enlarge the tricolor gamut. The results show that the ZnAl_(2)O_(4):Mn~(2+) phosphors may be considered as candidates for Hg-free lamps, plasma flat backlights, and field emission backlights for liquid crystal displays.
