摘要：
In this paper, the concentration regions and crystallization temperatures of alpha- and beta-BaB2O4 in the system BaB2O4-Na2O-Nd2O3 are determined. A stabilizing effect of the beta-BBO phase in the presence of Nd2O3 is detected. Several physical properties of the solutions important for the crystal growth processes are measured and the results discussed. beta-BBO : Nd3+ single crystals are grown and the Nd3+ concentration in the crystals are obtained. Finally, the Nd3+ absorption bands at room temperature in the region of 12 000-20 000 cm(-1) are determined. (C) 1999 Elsevier Science B.V. All rights reserved.
