Rare Earth Nanophosphors
Abstract
This project initiated a systematic investigation of doped nanodielectrics as optical materials in which strong scattering conditions offer prospects of new, low-voltage phosphors and high brightness surface lighting in the ultraviolet and visible spectral regions. The research effort succeeded in demonstrating not only new phosphors, but electrically-pumped stimulated emission in random powders and advances in the synthesis of dielectric nanophosphors suitable for bright source applications of many kinds, including flat panel display technologies, target identification, communication and authentication. As outlined in this report, results achieved during the project period considerable exceeded scientific objectives in both the quantum electronic and materials areas, by achieving the first continuous-wave laser operation at ultraviolet and visible wavelengths in several electrically-pumped powders. We also obtained the first direct evidence of stationary light in a structureless medium, that is, light of zero velocity created by a new approach to strong Anderson localization.
