Hydrothermal synthesis and photoluminescent properties of YV1 − xPxO4:Eu3+ (x = 0–1.0) nanophosphors
Source abstract
Abstract
A simple hydrothermal process has been proposed to systematically synthesize europium-doped yttrium phosphate-vanadates with general formula YV1 − xPxO4:Eu3+ (x = 0–1.0). All the YV1 − xPxO4:Eu3+ products were characterized by x-ray diffraction (XRD) and transmission electron microscopy (TEM), the results of which revealed they were single-phase tetragonal-structured nanocrystals with diameter of 20 nm and their cell parameter a exhibited a linear relationship with the x value. Photoluminescence (PL) excitation and emission intensities of the products were sensitive to the x value and the change of the PL intensity with x was a wave-like curve which reached the peak at x = 0.4 and 0.8. In addition, the x value had an obvious influence on the (5D0–7F2)/(5D0–7F1) intensity ratio of Eu3+.
