Abstract
Optical absorption spectra of BaF2−xClx:Eu in different states of optical storage were investigated. Three new difference absorption spectra bands were observed in ultraviolet region, which centered at 270, 315, and 378 nm. The bands at 270 and 315 nm were attributed to image and image centers, respectively. The band at 378 nm was tentatively attributed to hole-trap centers related to Cl− ions.
