Charge-trapping defects in crystalline solids play important roles in applications ranging from microelectronics, optical storage, sensing and quantum technologies. On one hand, depleting trapped charges in the host matrix reduces charge noise and enhances coherence of solid-state quantum emitters. On the other hand, stable charge traps can enable...
Space, radiotherapy, X-ray imaging/screening, nuclear reactors, large research facilities (linear accelerators and synchrotron radiation facilities), nuclear accidents. All these examples are associated with the need for monitoring high-energy radiation. Herein,...
The objective of this work is to evaluate the optically stimulated luminescence (OSL) lifetime dependence on different polycrystalline CaB6O10:Ln, Agx (Ln = Gd, Tb and Ce; x: % molar concentration) compounds. For the determination of the luminescence lifetimes, time-tagged time-resolved (TTTR) data of the OSL under pulsed stimulation were analyzed....
Alexandrite mineral (BeAl2O4:Cr³⁺) powder, incorporated in a fluorinated polymer, was prepared in the form of pellets. A mixture with 20 wt% of the alexandrite in the pellet had the luminescence behavior evaluated as a function of exposure to ionizing radiation using the optically stimulated luminescence (OSL) technique. The OSL measurements were e...
The knowledge of the thermoluminescence and radioluminescence spectra is important for understand-ing the nature of luminescence emitted by thermoluminescent dosimeters and scintillators. In view ofthat, an instrument that records these two types of spectra was developed. Mechanical and structuralparts as well as a description of each component of...
A new photostimulable phosphor based on Pb-doped CaB 6 O 10 was recently synthesized and its luminescence properties studied. This material is very promising exhibiting high sensitivity to ionizing radiation, comparable or surpassing commercially available luminescence materials such LiF:Mg,Ti and Al 2 O 3 :C with a dominant Thermoluminescence (TL)...
