Growth of two-dimensional KGd(WO4)2 nanorods by modified sol–gel Pechini method

KGd (WO4)2 nanocrystalline powder was obtained by modified sol–gel Pechini method. The synthesis procedure was optimized with TGA and DTA analyses. Synthesized polymeric resin was calcinated at 550 and 700 °C using resistive furnace in an open atmosphere. Crystallinity of annealed powder was confirmed using X-ray diffraction. Absorption peaks of FT-IR for gel and the annealed samples, at two different temperatures show the decomposition of citrate–ethylene glycol complex and formation of KGW particles. Raman analysis confirms that the derived particles have well constructed bridges of W–O–O–W. External morphology of the particles was analysed through SEM.
