Sm2O3: Eu3+ sol-gel ceramics obtained by the citrate sol-gel method

the 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...

Stoichiometric hydroxyapatite obtained by precipitation and sol gel processes

Se describen tres métodos para obtener hidroxiapatita (HA). La HA es una cerámica muy interesante por sus múltiples aplicaciones médicas. Los primeros dos métodos de precipitación parten de compuestos de calcio y fósforo, mientras que el tercer método es un proceso sol-gel que usa alcóxidos. Los productos fueron caracterizados y comparados entre sı́. Las diferencias observadas son importantes pa...

The 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...
