The growth and spectral analysis of mixed crystal of Yb‐doped Lu0.5Y0.5PO4 mixed crystals

A new kind of 5 at% Yb-doped Lu0.5Y0.5PO4 crystals were firstly grown by spontaneously nucleated high-temperature solution method using lead pyrophosphate (Pb2P2O7) as the solvent. The X-ray powder diffraction (XRPD) patterns recorded at room temperature showed the crystals possessed tetragonal xenotime structure. The polarized absorption spectra and the fluorescence spectra of Yb:LuxY1-xPO4 were measured at room temperature, respectively. The results show that Yb:LuxY1-xPO4 mixed crystal will be a promising laser material if the crystal size and quality is further improved.
