Abstract

Phase transition is harmful to the quality of Re doped Ba3Y(BO3)3 crystals. In order to obtain high quality Yb3+∶α-Ba3Y(BO3)3 crystal, Sr2+ ions co-doped Yb3+∶α-Ba3Y(BO3)3 crystal was grown with CZ method. Effect of various dopants and substitution sites on the growth and phase transition of Ba3Y(BO3)3 crystal were investigated. The phase transition temperature of 10at% Nd3+∶α-Ba3Y(BO3)3 crystal is 1099.6℃, which is lower than that of 10at% Yb3+∶α-Ba3Y(BO3)3 crystal (1145.3℃). Furthermore, the phase transition temperature of Nd3+∶α-Ba3Y(BO3)3 crystals is increased with the increase of the contentration of Nd3+ ions. For 10at%Yb3+∶α-Ba3Y(BO3)3 crystal, the melting point is increased and the phase transition temperature is decreased with the increase of the concentration of the codoped Sr2+ ions. The endothermic peak of phase transition disappears when the concentration of Sr2+ ions reaches 16at%, yet phase transition still exists with Sr2+ concentration of 5at% or 10at%.
