Optical and electron energy loss spectra of cadmium dichloride and lead dichloride crystals

Electronic structure of polycrystalline cadmium dichloride studied by X-ray spectroscopies and ab initio calculations

“…The estimated from Fig. 3(b) value of 6.6 eV, within the error limits, agrees with the accepted in literature "VB: chlorine p x,y e CB: cadmium s" interband transition 6.4e6.5 eV [3,5,27].…”

“…Its values could be estimated from optical spectra, and were found to be w5.7 eV [3] and w5.2 eV [11]. The fundamental optical absorption edge of the host CdCl 2 showed in [6] comes to 5.8 eV, whereas the lowest interband transitions value, estimated from the normalized energy loss functions of cadmium dichloride, varies from 6.2 to 6.5 eV [3,11,27]. Our calculated direct gap is about 40% smaller compared to the experimental value.…”
