THERMO-CHEMICAL SYNTHESIS OF ULTRAFINE POWDERS OF YTTRIUM OXIDE ACTIVATED BY EUROPIUM IONS
Abstract
A new approach to the synthesis of nanostructured yttrium oxide powders doped with europium ions by the method of combustionis is described. Carbohydrates (fructose, sucrose) and acetic acid were used as a fuel and hexamethylenetetramine – as additional fuel for ignition of the mixture. Based on the study of specific surface area, microstructure and morphology of the obtained powders, as well as after precursor calcination at 700, 900 and 1100 °C , it was found that specific surface area decreases with the increase of calcination temperature. This is due to the removal of weakly bound impurity groups (ОН, NO, СО2) from the surface of aggregates, compaction of the crystalline structure of the matrix particles and larger particle formation. In case of calcination at 700 °C, nanostructured particles with a size ranging from 39 nm (combustion in acetic acid) to 53 nm (burning in sucrose) are formed. Larger aggregates with particle sizes from 0.6 µm (in presence of sucrose) to 0.23 microns (in presence of acetic acid) are formed at 1100 °C. The powders obtained in such a way exhibit efficient luminescence properties in the red region of the spectrum upon excitation in the UV range (wavelength 250 nm).
