As is well known,the basic intrinsic properties of materials can be significant for their practical applications.In this work,the room-temperature absorption,transmittance,reflectance spectra,and relative photoelectricities parameters of the Mg4Ta2O9 crystals are demonstrated.Meanwhile,the polarized Raman spectra of Mg4Ta2O9 crystals are also described.The room-temperature photoluminescence (PL) and the temperature-dependent PL for Mg4Ta2O9 crystals are obtained.Significantly,we observe a phonon-participated PL process in Mg4Ta2O9.
