“…A similar behavior was observed for example in the ternary TeO 2 –GeO 2 –Ga 2 O 3 system. There, for a fixed TeO 2 /GeO 2 ratio, glasses with 16.7 mol% of Ga 2 O 3 exhibit a higher T g and a lower density than glasses without Ga 2 O 3 24 …”

Glasses in the TeO2–Ga2O3–M2O (M═Li, Na, or K) systems were synthesized by a melt‐quenching technique. The glass forming areas were delimited for each system. Systematic analyses were performed on two series of samples—the first one with a constant TeO2/Ga2O3 ratio of 85/15, that is, [(TeO2)0.85(Ga2O3)0.15]100−x[M2O]x with 0 ≤ x ≤ 25 (with a step of 5 mol%), the second one with a constant alkaline oxide concentration of 10 mol%, that is, [TeO2]90‐y[Ga2O3]y[M2O]10 with 5 ≤ y ≤ 15 (with step of 2.5 mol%). The values of the glass transition temperature, density, and optical transmission parameters (the positions of short‐ and long‐wavelength absorption edge and the maximum transmittance value) were determined. The changes in these parameters were studied for varying glass compositions. In addition, the values of refractive index were measured at various wavelengths across the whole transparency region reaching from the visible up to the mid‐infrared range.

“…This phenomenon suggests its possible application in tri-color white light emitting diodes as a red component. Praseodymium is also used with success in various types of phosphors due to the efficient reddish-orange emission of light [132]. For example, CdGeO 3 phosphor exhibits long persistent luminescence (LPL) after the short UV-irradiation.…”

Different types of ceramics and glass have been extensively investigated due to their application in brachytherapy, radiotherapy, nuclear medicine diagnosis, radioisotope power systems, radiation processing of food, geological and archaeological dating methods. This review collects the newest experimental results on the thermoluminescent (TL) properties of crystalline and glassy materials. The comparison of the physico-chemical properties shows that glassy materials could be a promising alternative for dosimetry purposes. Furthermore, the controlled process of crystallization can enhance the thermoluminescent properties of glasses. On the other hand, the article presents information on the ranges of the linear response to the dose of ionizing radiation and on the temperature positions of the thermoluminescent peaks depending on the doping concentration with rare-earth elements for crystalline and glassy materials. Additionally, the stability of dosimetric information storage (fading) and the optimal concentration of admixtures that cause the highest thermoluminescent response for a given type of the material are characterized. The influence of modifiers addition, i.e., rare-earth elements on the spectral properties of borate and phosphate glasses is described.
