Thermoluminescece properties of BeO:Mg nanoparticles produced by sol-gel method
Beryllium oxide (BeO) nanopowder was synthesized using sol-gel method and the effects of changes of chemical reagents were investigated. Because of tissue equivalence and other outstanding thermoluminescence (TL) properties of the bulk material in X and γ dosimetry, the applicability of this nanostructure in TL dosimetry was studied following irradiation to the 137 C...
متن کاملThe production of Ceramic Thin Films by Sol-Gel Method
The purpose of this work was to production of ceramic thin films by using of Sol-Gel process. For this purpose deposition of SiO2 on substrates of soda-lime glasses has been carried out. Coating treatments on prepared specimen were conducted in a Sol solution by means of dipping at various times. After drying and performing appropriate heat treatment on each sample, the thickness of coated laye...

متن کاملPreparation of Silica by Sol-Gel Method Using Formamide
In this work we obtained microporous and mesoporous silica gels by sol-gel processing. Tetraethylortosilicate (TEOS) was used as precursor. Nitric acid and hydrofluoric acid were used as catalysts. In order to study the affect of formamide as drying additive, we used a molar ratio alkoxide/formamide of 1/1. The performance of formamide in obtaining crack-free gels was evaluated through monolith...
متن کاملthe sol–gel technique
The sol–gel technique is a highly flexible technique for fabrication of oxide glasses, and various researchers have previously reported fluorescence studies of Er-doped sol–gel films and monoliths. Here we report the fabrication of Er-doped strip-loaded sol–gel silicate waveguides, using a silica–titania–alumina host composition, and Er concentrations up to f1.1=10 Er rcm, for possible applicat...
