A method is suggested for the determination of the optical depth of electron traps from the position of the exponential part of the decay curve of the flash sensitivity of a phosphor, considered as a function of the energy of infrared radiation used to illuminate the phosphor. This method is used to demonstrate that the difference between the optical and thermal depths of traps is independent of their depth and it is either 0.6 or 0.3 eV. Both these values may be manifested by the same trap depending on whether the liberation of electrons from the trap is adiabatic or nonadiabatic. It is also shown that the difference between the optical and thermal depths is related to the presence of ions in the crystal lattice because this difference vanishes in the case of covalent crystals.
