| Abstract: | The (RE):YVO_4 crystals with high quality optical properties and various dopant concentrations of Tm~(3 ), Er~(3 ) and Yb~(3 ) were grown using the Czochralski method. The room temperature fluorescence spectra have been measured, with 326 and 658 nm used as a pumping source. The fluorescence spectral properties were analysed with various dopant concentrations of rare-earth ions. Upconversion luminescence for various dopant concentrations was discussed. |
