| Abstract: | We perform a theoretical analysis of the spectra of two rather new kinds of fundamental luminescence in dielectrics: intraband electronic and interband hole emissions. The primary photon emitters are radiative transition of ionization-passive conduction-band electrons and valence-band holes. These types of luminescence have been observed and studied experimentally by the use of two powerful nanosecond and picosecond radiation sources: strong electronic accelerators and lasers with ultraviolet harmonic generators. Good agreement is obtained between the calculated spectra and the ones measured experimentally. Comparison of the results with the experimental data makes it possible to determine certain important parameters of the electron spectrum, in particular the upper boundary of the passive region for ionization of the conduction band in crystalline CsI.
