Abstract

This paper reports new data on flux growth and characterization of (R,Y)Al3(BO3)4 (R = Pr, Ho, Yb, Tm) single crystals obtained using potassium trimolybdate and lead fluoride based systems. The average R distribution coefficients were found to be 0.53 to 1.02 for different rare earth elements. Two morphological types of (Tm,Y)Al3(BO3)4 crystals were characterized. The visible luminescence spectra of (Pr,Y)Al3(BO3)4 and PrAl3(BO3)4 at 10 K and room temperature were measured..

Keywords
