Abstract : The optical spectra and crystal growth of CeO2 and ThO2 were studied to determine their potential usefulness as laser materials. Crystal growth was carried out by the flux technique. Phase equilibria and solubility determinations were made in order to select a flux for the growth of spectroscopic samples to eventually permit the growth of laser size crystals. Erbium, terbium, europium, samarium, dysprosium, manganese, and uranium were incorporated into single crystals of CeO2. Transmission measurements were made on all samples. When samples were observed to fluoresce with x-ray or UV excitation, their emission spectra, excitation spectra, and fluorescent lifetime were studied. The effect of charge compensation on these properties was also studied.
