Optical properties of trirutile structure MgTa2O6 single crystals grown by optical floating zone method

摘要

MgTa2O6 single crystals with trirutile structure have been employed as research objects in this paper. The absorbance spectra of the MgTa2O6 crystals are presented and the optical bandgap structures of MgTa2O6 are discussed. Both room temperature and temperature-dependent photoluminescence (PL) of MgTa2O6 single crystals are investigated. Significantly, there are two processes in the emission, and the optical phonon participated procedures are observed and described.
