Hydrothermal Synthesis of GdVO4:Eu3+ nanophosphors as down conversion in dye sensitized solar cells

GdVO4:Eu3+ nanosheets having tetragonal (t-) structure have been prepared using a facile hydrothermalmethod at 160 °C for 12 h. The as-prepared samples were characterized using powder X-ray diffraction (XRD),scanning electron microscopy (SEM), UV–vis diffuse reflectance spectroscopy (UV–vis) and photoluminescence (PL)spectroscopy. The room temperature photoluminescence spectrum showed that sheet-like GdVO4:Eu3+ nanocrystals(NCs) could absorb UV light and down convert it to visible light.
