Based on measurements of low-temperature (5 K) photoluminescence and reflectance spectra, changes in optical properties of a WSe2 monolayer resulting from vacuum annealing at a temperature of 300°С are shown. Initial monolayers were obtained by gold-assisted mechanical exfoliation from a bulk material. It is shown that annealing results in narrowing the resonance associated with the A-exciton, trion luminescence suppression, and the appearance of polarized impurity—defect luminescence.
