Scintillation, radioluminescence, photoluminescence, and thermoluminescence characteristics of Czochralski-grown Yb_xY_{1 - x}AlO₃ single crystals for x=0.02-0.45 are described. Under x-ray excitation, the intensity of Yb^{3 +} charge-transfer luminescence is increasing with x and reaches at room temperature more than 11% if Bi₄Ge₃O₁₂ for x=0.45 while at 80K it is over 170% of BGO for x>0.3. At room temperature, scintillation decay shows a dominant decay time of 0.8-0.9ns for x>0.3 significant slow components were detected
