摘要 研究了多种不同矿化剂对KBBF高温高压超临界水热条件下的相变的影响。归纳出KBe2BO3F2晶体"非整比溶解-非整比生长"的生长机制。通过这一机制对KBBF的结构多相性和非线性光学转换效率较低的问题有了新的认识。 The effect of different mineralizers on phase transition of KBe2BO3F2 under high temperature and pressure supercritical hydrothermal conditions was study. Growth mechanism of KBe2BO3F2 crystal, " Nonstoichiometric dissolution-nonstoichiometric growth",was summerized. Through this mechanism,a new understanding of the problem which is the structural heterogeneity and low nonlinear optical conversion efficiency of hydrothermal KBBF can be achieved.
