Spectrally resolved thermoluminescence measurements in fluorescence spectrometer

• Installation based on Perkin Elmer LS 55 fluorescence spectrometer is described.
• TL spectra registration technique during single heating cycle is presented.
• TL 3D plots for nitride materials exposed by UV irradiation are measured.

Registration of thermoluminescence (TL) spectra technique for irradiated samples in Perkin Elmer LS 55 spectrometer using developed high-temperature accessory during single heating cycle is shown. Functionality of serial instrument for RT–773 K temperature range is significantly widen. Spectrally resolved TL dependencies for h-BN micropowders and bulk AlN single crystals following UV irradiation are studied. TL spectral features of h-BN powders, synthesized by carbamide and plasma-chemical techniques, are determined and quantified. It is shown that the difference between TL curves obtained by the described and the standard modes does not exceed 10%.
