Cr,Mg:GSGG晶体生长、光谱性能及Cr4+形成机理的研究
Study of growth,spectra properties and Cr4+ formation mechanism of Cr,Mg:GSGGcrystal
摘要
Abstract
Cr,Mg:GSGG crystals are successfully grown by the Czochralski method.The influences of reducing- and oxidizing- annealing treatments on the absorption spectra of Cr,Mg:GSGG crystals are investigated.From the changes of their absorption spectra,it can be inferred that the Cr4+ ions are initially generated at octahedrally coordinated sites,and then exchange positions with tetrahedral Ga3+ ions in neighboring sites under heat exciting.Differences between absorption spectra also suggest that Mg2+ ions can improve the concentration of tetrahedral Cr4+ ions.关键词
