| Abstract: | Good quality crystals ZnWO4 activated with Er3+ have been grown by means of Czochralski method and characterized using optical spectroscopy techniques. XRD, absorption spectra, fluorescence spectrum are presented and the Judd-Ofelt intensity parameters Ω2, Ω4, and Ω6 are obtained to be 6.76×10-20, 0.37×10-20, and 0.50×10-20 cm2, respectively. Along crystallographic axes, refractive indices are presented. The fluorescence decay time of the 4I13/2 level has also been investigated and shows an exponential behavior with a lifetime value of 5.52 ms. The crystal is potentially used for green and infrared eye-safe lasers. |
