The upscaling of perovskite solar cells is one of the challenges that must be addressed to pave the way toward the commercial development of this technology. As for other thin-film photovoltaic technologies, upscaling requires the fabrication of modules composed of series-connected cells. In this work we demonstrate for the first time the interconn...

The current study presents rhyolite as a novel and promising natural thermoluminescence emission (TL) material. The work focused on enhancing the TL sensitivity of rhyolite via optimization of the processing conditions: annealing and pre-dose effect. The glow curves of irradiated rhyolite sample showed a single peak of about 110°C at 5°C sec-1 heat...

AbstractThe mechanisms of photo- and thermoluminescence processes in cation-deficient submicron AlN crystals after UV excitation are studied. The observed emission spectra represent a superposition of bands peaking at 3.0 and 2.5 eV. These spectral features are related to electronic transitions with participation of ON impurity centers and oxygen–v...

AbstractThe thermoluminescent properties of PbCd2B6O12crystal phosphors doped with Eu3+ ions and exposed to β-ray irradiation are investigated. Polycrystalline samples of the initial matrix and solid solutions based on it were synthesized by solid-phase reactions and characterized by X-ray phase analysis, IR spectroscopy, and differential scanning ...
This work is dedicated to the development of new types of composite thermoluminescent (TL) detectors for simultaneous registration of the different components of ionization radiation based on the single crystalline films (SCFs) of Ce3+-doped Lu3&minus / xGdxAl5O12:Ce (x = 0&ndash / 1.5) garnet and Y3Al5O12:Ce (YAG:Ce) substrates using the liquid ph...

Thermoluminescence (TL) properties of La2O3: Dy3+, Li+, and La2O3: Eu3+, Li+, exposed to 5.12 Gy of beta radiation, and recorded at different heating rates 0.5, 1, 2, 3, 4, and 5 °C s−1 (from Molefe et al., paper 2019), were analyzed and the trap parameters were determined in this study. These parameters include the order of kinetics b , the activa...

The method of measuring doses based on the thermoluminescence phenomenon is not an absolute method. For this reason, to obtain correct results, it is necessary to calibrate detectors in the known radiation field. This paper presents a method for calibrating thermoluminescent detectors used in the measurement of personal dose equivalents (Hp(0.07)) ...

Rare-earth ions play an important role in eco-friendly solid-state lighting for the lighting industry. In the present study we were interested in Eu3+ ion-doped inorganic phosphors for near ultraviolet (UV) excited light-emitting diode (LED) applications. Eu3+ ion-activated SrYAl3 O7 phosphors were prepared using a solution combustion route at 550°...
