The polarization absorption spectra of Pr³⁺-doped GdScO₃ have been measured. Polarized emission spectra and fluorescence decay from the ³P₀ upper level have been investigated. The strongest absorption peaks are located at 448 nm for a, b and c polarization, the absorption cross sections are 1.29 × 10⁻²⁰ cm², 0.98 × 10⁻²⁰ cm² and 1.57 × 10⁻²⁰ cm², respectively. The maximum emission cross section is located at 662 nm, which is 18.55 × 10⁻²⁰ cm² (a polarization), 12.74 × 10⁻²⁰ cm² (b polarization) and 22.41 × 10⁻²⁰ cm² (c polarization), and the FWHM is 10.02 nm, 9.38 nm and 10.14 nm, respectively. The fluorescence lifetime of ³P₀ level is 12.39 μs. Those results indicated that Pr³⁺-doped GdScO₃ crystal grown by the Czochralski method is a potential laser medium for visible laser operation.
