Abstract
The crystal field split levels of the 4I9/2 and 4I11/2 states of CaF2:Nd3+ were determined from the fluorescence and absorption spectra. The data are compared to an energy‐level calculation for the case of a weak cubic field containing fourth‐ and sixth‐order terms. Both the absorption and fluorescence spectra were found to be strongly concentration dependent at relatively low concentrations (0.01 mole %).Keywords
