| Abstract |
Nanocomposites (nanocrystals) of KY(WO4)2 and KY(WO4)2+1% mol Yb were
synthesized using a Complex Sol-Gel Process (CSGP). A chemical treatment with concentrated
nitric acid and hydrogen peroxide was used to reduce the decarbonisation temperature. The
expected monoclinic phase C2/c of the KYW of the nanocomposite powder was confirmed using
XDR. From the X-ray diffraction measurements, the unit cell parameters and the size of
nanoparticles was determined. Electron spin resonance studies in the X band were carried out on
KYW and KYW:Yb nanocrystals. The sintered samples were made with using the high pressure
technique at temperatures up to 600oC. In addition chemical analysis, X-ray diffraction
measurements and ESR investigations were carried out on the sintered samples. |
