Synthesis and Growth of A Novel NLO Crystal K2Al2B2O7
【摘要】 本文以高温固相反应合成了K2 Al2 B2 O7(KABO) ;以自发成核的方法探索了KABO晶体生长的助熔剂体系 ,NaF为KABO晶体生长的最适宜助熔剂体系 ,适宜配比为KABO∶NaF =1∶2 ,讨论了籽晶方向对晶体生长的影响 ,[110 ]方向是KABO晶体生长的最佳籽晶方向 ;运用顶部籽晶生长技术以NaF为助熔剂成功生长出尺寸达 5 0mm× 2 0mm× 17mm ,重 30g的高光学质量透明单晶
【Abstract】 K 2Al 2B 2O 7(KABO)was synthesized by a solid state reaction in high temperature.The flux systems for the growth of KABO crystals were investigated with a spontaneous nucleation method.NaF is available for the growth of KABO crystals.The suitable proportion is KABO∶NaF=1∶2.The effects of seed directions on the growth of KABO crystals are discussed.And seeds along direction are favorable for the growth of KABO crystals.A crystal with dimensions of 50mm×20mm×17mm and weight of 30g was successfully grown with a top seeded growth method (TSGM) using NaF as a flux.
