摘要：

The co-precipitation reaction soft chemistry method was employed to prepare fine Y-PO4:Dy3+ phosphor particles calcined at 950 degrees 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 40nm. The characteristic transitions of Dy3+ due to F-4(9/2) -> H-6(15/2) (blue) and F-4(9/2) -> H-6(13/2) (yellow) were detected in the emission spectra. (c) 2007 Published by Elsevier B.V.
