【 摘 要 】

Thermoluminescence (TL) properties of Hausmannite thin films deposited onto glass substrates have been studied. The thin Mn2+Mn3+2O4films were grown at 350°C on 1×2 cm2glass substrate by a spray pyrolysis technique. UV light from a XBO lamp was used to induce thermoluminescence in the film and the thermoluminescence properties of the Hausmannite layer were studied measuring the intensities of the TL peaks from the glow-curve deconvolution. The TL kinetic parameters of the Hausmannite were obtained from the TL glow curves analysis. The spectral emission of the Mn2+Mn3+2O4layer has been studied using interference filters. The TL peak-fading assessment of the Hausmannite layer revealed that the peaks at 110°C, at 142°C and 194°C have relatively long fading. The analysis of the thermoluminescence properties of the Hausmannite thin films deposited onto glass substrates shows that they possess very good sensitivity for UV emission and could be used for quantitative measurements of UV light.
