Determination of the oscillator strength of F centres in KBr-In by photostimulated luminescence

Abstract

Usingthephotostimulatedluminescenceof !F-In?*)defect pairsinKBr-lnavery sensitive method for the determination oi the oscillator strength of F centres has been proposed. Its main advantage is that there is no need to know any absorption characteristics nor the concentration of F centres. Some criteria for the applicability of this method are analvsed

Observation of Free Electron Cyclotron Resonance in NaAlSi3O8 Feldspar: Direct Determination of the Effective Electron Mass

“…The features of this centre have striking similarities to that of the F centres in alkali halides (e.g. Kalnins et al [29]). Because the IR resonance is so important in luminescence radiation dosimetry [5,6,8], we seek briefly to use the effective electron mass measurements to try to ellucidate further on its origin.…”

The Observation of a New D‐Absorption Band in KBr–In Crystals

“…3). Let us use now the modified Smakula formula for the determination of the oscillator strength via the effective absorption cross-section oM in the absorption band peak [12], which for the Lorentz local field and Gaussian shape of the…”
