Abstract

The results of luminescence studies conducted on the same samples of GaP over a 40-year period are discussed. The results strongly imply that periodic ordering of impurities improved the overall optical and mechanical properties of the material over time. Forty years after preparation, "hot" luminescence spectra in gallium phosphide (GaP) are similar to those for nanocrystals. The aged pure and N-doped crystals exhibit stimulated emission at 300 K. The aged GaP:N:Sm at room temperature generates bright green or yellow and red tunable luminescence. These results correlate with Raman light scattering and microhardness data obtained from the same crystals. © 2009 TMS.
