Abstract:

This project investigated the optical emission of new materials doped with Ce3 for indications of practical alternatives to conventional excitation of Ce light sources. Two approaches were tried one was based on Nd3 upconversion dynamics in co-doped samples, and the other utilized electron beam pumping of Ce-doped nanopowders. Electron excitation showed exceptional promise for achieving bright emission from powders in which particle sizes averaged less than 50 nm.
