“…Recently the excitation of the Cs+5p level was independently studied for different Cs halides by measuring reflection spectra [l, 21 and absorption spectra [3,4] with higher resolution and, partly, a t lower temperature than before. I n these experiments many new interesting features were observed in comparison to older optical absorption work [5] or electron energy loss measurements [6]. However, some apparent inconsistencies still remained between different authors' results, e.g.…”

The excitation of the Cs-5p core level in Cs halides which starts a t about 13 eV was studied by measuring the reflection spectra of evaporated films between 12.5 and 26 eV at room temperature and a t 30 K. Synchrotron radiation was used as a light source. In comparison to the spectra at room temperature new remarkable fine structure was found at 30 K. The very complex spectra are discussed with regard to band calculations including excitons associated with critical points. I n a complementary view the spectra are compared with transitions of the free Cs+ ion. A sideband at the high energy part of the most prominent exciton was observed for every Cs halide. It is, presumably, caused by excitonphonon interaction.

“…This is the case for, e.g., [Fe(CN) 2 (diimine) 2 ] complexes, where steric constraints arising from inter-ligand repulsions between the two diimine ligands impose cis-geometry on the cyanide ligands. Analogous solvation patterns apply to organometallic analogues [M(CO) 4 (diimine)] (M = Cr, Mo or W) [7,8] and to pentacyanoferrates [Fe(CN) 5 L] n- [9].…”

“…However, in the EUV and FUV spectral range thin films of these materials have not yet been fully characterized. Eby et al, 8 Teegarden and Baldini, 9 and Saito et al 10 performed absorption measurements for many alkalihalide thin films, although neither optical constants nor absorption coefficients were determined. Lu and McDonald 11 measured CsI thin-film transmittance at wavelengths longer than 115 nm.…”

The optical constants of thin films of CsI, KI, and KBr and the quantum efficiency (QE) of planar photocathodes made with these alkali halides in the 53.6-174.4-nm spectral range are presented. The optical constants were obtained from measurements of the reflectance as a function of incidence angle. The effect of film heating and exposure to UV irradiation on the optical properties and on the QE of the three alkali halides was investigated. KBr was found to be the most stable material for both heating and UV irradiation. KI appeared to be close to temperature stable, whereas UV exposure affected its optical constants. CsI optical constants changed after 420 K heating and after UV exposure. The changes in the optical constants were related to the QE changes, and a certain correlation between both variations was determined. However, it was also demonstrated that the QE changes cannot be explained solely by the changes in optical constants.
