The synthesis and optical characterizations of CaLaGa3O7 crystals with different Er dopant concentration are reported. The optical parameters related to absorption and emission cross-sections were evaluated and compared. It was found that the NIR fluorescence weakens, at the same time Mid-IR fluorescence intensity strengthens with the increment of Er3+ ion dopant concentration in Er: CaLaGa3O7 crystals...
Single crystals of pure and Er3+ doped CaLaGa3O7 were firstly grown by the Czochralski technology. The structure of CaLaGa3O7 was investigated. The electronic structures of CaLaGa3O7 crystal were performed by using first-principles calculations based on density functional theory (DFT) methods. Its band structure and density of states were presented. The polarized absorption, emission spectra including...
