Synthesis and photoluminescent features of Eu3+-doped NaGd(WO4)2 nanophosphors
Source abstract
Abstract
Abstract The preparation of Eu3+-doped NaGd(WO4)2 (NGW) nanophosphors was conducted by using a coprecipitation method. The characterization of the final products was performed in this work. The X-ray diffraction (XRD) results presented that our prepared NGW:Eu3+ phosphors are single-phase and belong to the tetragonal system, and the field emission scanning electron microscopy (FE-SEM) study showed that our synthesized samples consist of many irregular rod-like particles. The characteristic emissions due to Eu3+ transitions of 5D0→7FJ(J = 1–4) were observed upon 395 nm excitation. Based on the Huang and Van Uitert models, the impact of Eu3+ concentration on the luminescent intensity was studied. The concentration quenching of Eu3+ ions in NGW nanophosphors was contributed to the electric dipole-dipole interaction. The red light emission of NGW:Eu3+ nanophosphors indicates the promising applications for white LED, flat panel displays and biological field.
