Thermostimulated luminescence of colloidal Ag2S quantum dots

Ag2S Nanoheaters with Multiparameter Sensing for Reliable Thermal Feedback during In Vivo Tumor Therapy

“…This, in turn, can be achieved by the thermally sensitive properties of Ag 2 S NPs. [ 19 ] Figure a includes the emission spectra obtained from a colloidal solution of Ag 2 S NPs in PBS under 808 nm laser excitation, as obtained at different temperatures. An intense thermal quenching accompanied by a red‐shift of this emission band due to the temperature increment in the bandgap energy is evidenced.…”

“…Thus, the curves of thermoluminescence were representing the difference of luminescence intensities for the heating and cooling process. 38,39 3 Results and discussion…”

Ag2S QDs/Si Heterostructure-Based Ultrasensitive SWIR Range Detector

“…The Ag2S QDs used have size-dependent photoluminescence in the region of 600-1100 нм ( A few groups of shallow trap states with energy depths of 0.06-0.12 eV involved in non-radiative carrier capture were detected in Ag 2 S QDs with different sizes by the method of thermally stimulated luminescence (TSL), which is detailed and described in [45]. In the TSL modification used by us, the sample with constant photoexcitation was cooled to the temperature of liquid nitrogen, where it was kept for some time (about 5 min); then, it was heated to the initial temperature.…”

“…The resulting difference is due to the thermal release of charge carriers localized to trap states. Then, using the kinetic model of the process, the depths of the corresponding trap states were determined [ 45 ].…”
