Abstract

The co-precipitation reaction soft chemistry method was employed to prepare fine YPO₄:Dy³⁺ phosphor particles calcined at 950 °C. Adjusting appropriate pH and introducing lithium may greatly affect the particle size of the product and further affect the luminescence intensity. The as-prepared samples were characterized by X-ray diffraction (XRD), transmission electron micrograph (TEM) and photoluminescence (PL) spectroscopy. The obtained YPO₄ nanocrystals appeared to be spherical with some agglomeration and their sizes ranged from 20 to 40 nm. The characteristic transitions of Dy³⁺ due to ⁴F_9/2→⁶H_15/2 (blue) and ⁴F_9/2→⁶H_13/2 (yellow) were detected in the emission spectra.
