High energy absorption spectra of the first row transition metal ions in the lithium chloride single crystal host
Abstract
A systematic study was conducted in order to examine the first row transition metal ions, in the 2+ oxidation state, substitutionally doped into the simple cubic LiCl crystal system. A modified bridgeman method was used in the crystal growth procedure. The exact conditions for preparation of each doped single crystal are given. The LiCl lattice provides high solid solubility for the impurities of interest. It also transmits energy farther into the UV than does any other chloride host. However, due to the extreme affinity of LiCl for water, special techniques and equipment were developed for the preparation of single crystal specimens for spectroscopic study. The resulting crystals were found to be of very high purity, containing only the doped ion of interest. This allowed an unambiguous interpretation of the observed absorption bands in the ultraviolet region. The UV absorption spectra are given for each impurity ion at 10 K, 80 K, and 300 K.
