On the luminescence origin in Y2SiO5:Ce and Lu2SiO5:Ce single crystals
Original language description
Photoluminescence characteristics of single crystals of Ce3+ - doped rare-earth oxyorthosilicates RE2SiO5 (RE: Y, Lu) with different Ce3+ concentrations are studied in the 4.2-500 K temperature range by the steady-state and time-resolved spectroscopy methods. On the basis of the obtained results and analysis of the literature data, the suggestion is made that the dominating higher-energy (violet) doublet emission band of Y2SiO5:Ce and Lu2SiO5:Ce (denoted earlier as the Ce1 emission) arises from the Ce3+ ions substituting for the host crystal lattice rare-earth RE3+ ions in both the RE1 and the RE2 lattice sites. The weaker lower-energy (blue) broad emission band is ascribed to the dimer Ce3+ - related centers.
