The unidirectional sodium trimetaphosphate doped glycine phosphite (STM-GPI) single crystals were grown by a modified thermal gradient solution (TGS) growth method. The single crystals were grown with diameters ranging from 18 to 35 mm. The intrinsic and extrinsic point defects were created due to the doping effect. The phase changes in lattice parameter values and intensity of reflections have been analysed in this study. The effect of point defects due to STM doping in glycine phosphite has been studied. The full width at half maximum (FWHM) of the high-resolution diffraction curves was confirmed as 70 arc s. The defected single crystal shows a lower laser damage threshold value. The bending and stretching vibrations were changed in functional groups. The changes on the surface of the crystal were analysed with real-time growth. The Curie temperature and cutoff wavelength were measured.

三偏磷酸钠对改良热梯度法生长亚磷酸甘氨酸单晶的影响

单向三偏磷酸钠掺杂的甘氨酸亚磷酸酯 (STM-GPI) 单晶通过改进的热梯度溶液 (TGS) 生长方法生长。单晶生长的直径范围为 18 至 35 毫米。由于掺杂效应,产生了内在和外在点缺陷。本研究分析了晶格参数值和反射强度的相变。已经研究了由于甘氨酸亚磷酸酯中 STM 掺杂引起的点缺陷的影响。高分辨率衍射曲线的半峰全宽 (FWHM) 被确认为 70 弧秒。有缺陷的单晶显示出较低的激光损伤阈值。弯曲和拉伸振动在官能团中发生了变化。通过实时生长分析晶体表面的变化。
