Synthesis, characterisation and photoluminescence of nanocrystalline calcium tungstate

Synthesis, characterisation and photoluminescence of nanocrystalline calcium tungstate

Calcium tungstate nanocrystalline was successfully synthesised via a microwave irradiation method using Ca(NO3)2and Na2WO4in ethylene glycol, without the requirement of any calcination. The product was analysed by X-ray diffraction (XRD), Raman spectroscopy, Fourier transform infrared spectroscopy (...
