Abstract

Tetragonal phase CaGd2(MoO4)4:Eu3+ with ovoid like hierarchical structures were prepared via employing ethylene diamine tetra acetic acid (EDTA) using the hydrothermal route at 200 °C for 24 h. X-ray diffraction patterns and field emission scanning microscopy images were used to characterize the crystal structure, phase, morphology and size of the nano samples. X-ray photo electron spectroscopy (XPS) and energy dispersive X-ray spectroscopy (Edax) confirmed the presence of elements in phosphor samples. The PL properties of the phosphors were studied thoroughly. The photophysical properties of the samples were examined by the Judd–Ofelt theory. The CIE coordinates of the prepared phosphor samples illustrate that red light emission can be realized from CaGd2(MoO4)4:Eu3+ phosphor and it coexists very close to NTSC standard values. All these results show that ovoid like CaGd2(MoO4)4:Eu3+ micro/nanophosphor is a promising material for display applications.
