Glasses are promising functional materials as phosphors with an aim to use in radiation measurements because of easy shaping, low fabrication cost and large volume possibility. In this study, Eu3+-activated gallate glasses having glass compositions 20K2O–11La2O3–(69−x)Ga2O3–xEu2O3 (x = 0.1–1.0) were synthesized, their photoluminescence, scintillation thermoluminescent characteristics investigat...

An antimony oxide based monolithic glass with very high Sb2O3 content (70 mol%) in the system K2O-B2O3-Sb2O3 (KBS) has been prepared for the first time. Its phonon energy (602 cm(-1)), evaluated by infrared reflection spectroscopy, is found to be very close to that of fluoride glasses (500-600 cm(-1)). After doping with different rare-earth ions, their UV-vis absorption and photoluminescence pr...

Returning straw to the field is most significant utilization technique for China’s green development. It can provide nutrients crop growth and improve soil organic matter content. However, there are no standard parameters measuring nutrient content of directly returned field. In addition, in disregarded least researched. Therefore, address these issues, current research examines main compositio...

The accumulated knowledge about the structure of a substance makes it possible to control its properties, including purposeful selection raw materials and for creation, vice versa, based on natural or artificial material composition, predict physical chemical properties. This approach allows choosing replacement rare even scarce types mineral produce particular product. analysis literature data...

In order to study the effect of R2O/Al2O3 (where R=Na or K), SiO2/Al2O3, Na2O/K2O and H2O/R2O molar ratios on the compressive strength (CS) of Metakaolin base geopolymers, more than forty data were gathered from literature. To increase the number of data, some experiments were also designed. The resulted data were utilized to train and test the three layer artificial neural network (ANN). Bayes...
