In this work, GdAlO3:Pr3+ was successfully prepared by the Pechini method at lower temperatures when compared to others methods such as solid-state synthesis and sol-gel process. In accordance to the XRD data, the fully crystalline single-phase GdAlO3 could be obtained at 900 °C. Luminescence measurements indicate Gd → Pr3+ energy transfer. In the emission spectra, the 3P0 →3 H4 (blue emission) and...
