“…Additional optical absorption measurements were made as a function of wavelength and temperature by Schneider and 0' Bryan12 and others. 13-17 18 More recently Eby, Teegarden, and Dutton have 6 measured the absorption spectra of evaporated films of the alkali halides, with the exception of LiF, at room temperature and have also extended the measurements to liquid nitrogen temperature. Figure 1 shows the absorption spectra of KCl, KBr, and RbI.…”

“…После основополагающей работы [11] были осуществ-лены прецизионные исследования спектров поглощения и отражения всех ЩГК в широком диапазоне темпе-ратур начиная от 10 K, а с помощью дисперсионных соотношений Крамерса−Кронига из спектров отражения монокристаллов были вычислены спектры оптических констант (см., например, [36][37][38][39][40][41][42]). Было показано, что полосы низкоэнергетических экситонов имеют форму асимметричного лоренциана, характерного для свобод-ных экситонов.…”

“…5. 8 ev • 47 As the intensity of excitation increased, the equilibrium density of I2 molecule ions increased while the density of the other electron traps (associated with impurities) remained constant; this situation would lead to an increase in the yield of the· 2950A emission band as the intensity of the excitation increases. For excita,tion with photons having an.energy which is less than the band gap, it seems reasonable to assume that I; centers are not fanned with a high effi;.. ciency b.ecause of the small probability that the excited electrons will reach the conduction band.…”
