Abstract Upconversion materials have several advantages for many applications due to their great potential in converting infrared light to visible. For practical use, it is necessary to achieve high intensity of UC luminescence, so the studies of the optimal synthesis parameters for upconversion nanoparticles are still going on.

Luminescence properties of calcium and strontium molybdates, undoped as well as doped with Nd3+ ions were studied. The influence of temperature on the energy transfer processes from the intrinsic emission centers to activator is shown on the basis of the analysis of the temperature dependencies of luminescence spectra and decay kinetics. It is concluded that the studied compounds are promising for non-contact luminescent thermometry in a wide temperature range.

Delayed luminescence from organisms informs oxidative stress that may be modulable by external stimulations.

Abstract:
The investigation of the luminescent properties of nonstoichiometric spinel compositions of MgO·2,5Al2O3 irradiated in direct and scattered beams of 12 MeV electrons on M-30 microtron are given. The phosphorescence decay kinetics of these compounds that occur after irradiation have been studied. It was found that the kinetics of induced luminescence can be described the Becquerel’s hyperbola. The degree parameter of this hyperbola is increased with increasing the dose of radiation. The regularities of the thermoluminescence peak change in the range of 110-250ºC with the dose are investigated.

Abstract:
This study delves into the intricacies of isothermal decay analysis applied to thermoluminescence (TL) peaks, focusing on determining kinetic parameters. The study challenges the conformity of the trap responsible for the ITL signals to first, second, or general-order kinetics, supported by the non-conforming decay pattern and the inference of two overlapping first-order TL peaks. This work enhances the understanding of TL peaks and establishes a reliable methodology for characterizing luminescence mechanisms in materials, contributing to advancements in luminescence dosimetry research.

Abstract:
A granitic feldspar is well-ordered and has a stable thermoluminescence signal enabling its dating with high reliability. In contrast, a volcanic feldspar (sanidine) exhibits a slight cristallographic disorder and an anomalously fast fading of the thermoluminescence signal (Visocekas et al. 2014). It is shown here how disorder changes the decay of the signal and enhances the kinetics, while the increase in the microscopic complexity plays no role.

On the example of InP/InAsP/InP nanowires, the role of theoretical models in the photodynamics study of hybrid semiconductor structures is considered. The photodynamics of luminescence of an array of InP/InAsP/InP nanowires formed by molecular beam epitaxy on a Si (III) substrate was studied. Based on a comparison of several kinetic models, including the use of poly-exponential and stretched-exponential functions, the analysis of experimental data is carried out. Experiments were performed by excitation with laser radiation of 633 nm at room temperature. It has been shown that the luminescence
