Abstract
Inthisresearch,silicananoparticleswere synthesized ymicroemulsionmethod. Thengadoliniumcarbonatewascoated onsilicananoparticles by depositiontechnique.After thatTiO2wascoatedbydeposition techniqueonsilica/gadolinium carbonatenanoparticles.The results of infrared spectroscopy (FT-IR) on silica/gadolinium carbonatesamples showed carbonate bonds. The results of X-ray diffraction (XRD) test on samples of silica/gadolinium carbonatethat had been calcined at 600 0C for 2 h, showed that silica and gadolinium carbonate phases are amorphous and with increasing calcination temperature, gadolinium oxide crystalline phase is formed. For TiO2 coatings process, the effect of TBOT concentration, the...
