Abstract―

The possibility of using gadolinium titanate single crystals in quantum electronics is considered. This compound has been chosen as a result of consideration of possible stable chemical compounds in the gadolinium oxide–titanium oxide system. The technology of growing gadolinium titanate single crystals doped with neodymium ions by optical zone melting, which excludes the possibility of contaminating material during crystal growth, is developed. Absorption and luminescence spectra in the range from helium to room temperature and stimulated emission in this material with neodymium ions used as activator centers have been studied. An energy-level diagram of Nd³⁺ ion in the gadolinium titanate lattice is constructed based on the analysis of spectroscopic data. It is shown that there may be at least three types of optical centers containing Nd³⁺ ions in the gadolinium titanate lattice.

钛酸Ga晶体晶格中钕离子的光谱性质

摘要―

考虑了在量子电子学中使用钛酸g单晶的可能性。选择该化合物是因为考虑了氧化oxide-氧化钛体系中可能存在的稳定化合物。开发了通过光学区熔化来生长掺有钕离子的钛酸g单晶的技术，该技术排除了晶体生长过程中污染材料的可能性。已经研究了从氦气到室温的吸收光谱和发光光谱，以及以钕离子为活化剂中心的这种材料在受激发射中的发射光谱。Nd ³⁺的能级图基于光谱数据分析，构建了钛酸晶格中的离子。结果表明，在钛酸g晶格中可能存在至少三种类型的包含Nd ³⁺离子的光学中心。
