摘要: 在光谱的可见和近红外区域内系统地研究了无水NdCl3和无水PrCl3(含0.1％NdCl3)单晶体中Nd3+的吸收光谱。其吸收光谱线群的结构与含2％NdCl3的无水LaCl3单晶体中的Nd3+的吸收光谱一样,只是所有相应的吸收光谱线群有一个向光谱长波端的整体移位。相应上子能级间的移位(相对于基态)与单晶体原胞长度c0成正比(见图3)。

Abstract: The absorption spectra of Nd3+ in pure anhydrous neodymium chloride crystals and in anhydrous praseodymium chloride crystals (containing 0.1% NdCl3) have been examined systematically examined. The structures of the groups of their absorption lines are found to be similar to those of Nd3+ in NdCl3 crystals diluted by LaCl3 (containing 2% NaCl3 in LaCl3), except for a shift of the spectrum towards the long wave side. The shifts (relative to the ground state) of these corresponding sub-levels are proportional to the length of unit cell of the single crystals.
