Abstract

The nano/microstructured Y0.95Eu0.05PO4 have been hydrothermally synthesized by changing the pH value and PO4/RE molar ratio. The structures and morphologies of the as-synthesized Y0.95Eu0.05PO4 have been investigated by X-ray powder diffraction (XRD), thermogravimetric analysis (TGA) and field-emission scanning electron microscopy (FE-SEM). The results indicate that the small nanoparticals formed at lower pH value and the microparticals obtained at higher pH value. A possible formation mechanism of the products was also proposed. The luminescent properties of the products prepared with different pH values have been studied. When the pH value from 1.0 to 8.0, the products of luminescence intensity was decreased..
