In accordance to the XRD data, the fully crystalline single-phase GdAlO3 could be obtained at 900 degrees C. Luminescence measurements indicate Gd -> Pr3+ energy transfer. In the emission spectra, the P-3(0) ->(3) H-4 (blue emission) and D-1(2) ->(3) H-4 (red emission) transitions of Pr3+ ions can be observed and the ratio between their intensities depends on the Pr3+ content due to the cross-relaxation phenomenon.1260-1263engGadolinium compoundsluminescencepraseodymiumscintillation detectorsCarta10.1109/TNS.2009.2036177WOS:000278812200022Acesso aberto42848093425462872034352556339501
