Title
Crystal Growth And Spectroscopic Properties Of Cr4+ In Ca2Al2Sio7 And Ca2Ga2Sio7
Abstract
We report crystal growth, spectroscopic, and stimulated emission investigations of Cr4+ in the melilites Ca2Al2SiO7 (CAS) and Ca2Ga2SiO7 (CGS). The predominant absorption and emission features are similar to those of Cr:forsterite grown in an oxidizing atmosphere, consistent with the similarity of the tetrahedral cation sites in these crystals. Secondary emissiom and excitation bands of unknown origin are observed in both melilites. All emission is strongly quenched at room temperature, due primarily to intraionic processes in CAS and energy transfer in CGS. No stimulated emission has been observed in either material. © 1992.
