A high-temperature accessory for measurements of the spectral characteristics of thermoluminescence

A high-temperature accessory for a commercial fluorescence spectrometer, which allows performing luminescent studies of solid samples in the range up to 773 K, is described. The modes of linear heating with rates of 0.1–10 K/s, temperature control with an accuracy of <0.5 K, and an arbitrary temperaturetime profile were realized. The operation of a Perkin Elmer LS55 spectrometer at high temperatures was demonstrated by the example of investigating the spectral and kinetic regularities of thermoluminescence in hexagonal boron nitride using the developed module.
