title: A Garnet-Based Ca2YZr2Al3O12:Eu3+Red-Emitting Phosphor for n-UV Light Emitting Diodes and Field Emission Displays: Electronic Structure and Luminescence Properties.
abstract: A series of Ca2YZr2Al3O12:Eu3+(CYZA) phosphors were successfully synthesized through conventional solid-state method. The electronic structure and their photoluminescence or cathodoluminescence properties were investigated in detail. Under n-UV excitation, the CYZA:Eu3+exhibits more intense red emission than the commercial Y2O3:Eu3+phosphor. A WLED lamp with good color render index was obtained by fabricating the phosphor with BAM:Eu2+and LuAG:Ce3+phosphors. The phosphor also exhibits red emission with high current saturation and high resistance under low voltage electron bombardment. The degradation resistance can be compared to the commercial Y2O3:Eu3+phosphor. All the results indicate that the CYZA:Eu3+has potential applications in both white LEDs and FEDs.
