Effect of processing parameters on luminescence of combustion-synthesized, rare earth-activated Y{sub 3}Al{sub 5}O{sub 12} phosphors
- Univ. of California, San Diego, CA (United States); and others
A novel ceramic synthesis technique, combustion synthesis, was explored to produce Y{sub 3}Al{sub 5}O{sub 12} (YAG) phosphors with improved physical and luminescent properties. The rare-earth ions Eu{sup 3+}, Tb{sup 3+}, and Tm{sup 3+} were used as activators for red, green, and blue emission respectively. The combustion synthesis technique involves the reaction of metal nitrates (oxidizers) and an organic fuel at 500{degrees}C. Resulting powders are well-crystallized, with small particle size. Luminous intensity was observed using photoluminescence measurements. the effects of processing parameters such as type of fuel, ignition temperature, and activator concentration were studied. Particle sizes were found to range from 0.4 to 3 {mu}m, depending upon the processing parameters.
