Abstract
Well-defined GdPO4 nanocrystals were successfully prepared through the facile hydrothermal synthesis route followed by a heat treatment. The microstructure, morphologies and photoluminescence properties of as-prepared samples were investigated via X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), fourier transform infrared spectroscopy (FT-IR), photoluminescence (PL) spectroscopy and luminescence decay, which were significantly affected by the reaction conditions (phosphorus source, acidity of hydrothermal process and surfactants). It is found that Sodium dodecyl sulfate (SDS) as a shape modifier has the dynamic effect by adjusting the growth rate of different facets, resulting in morphology transformation of GdPO4·H2O from the nanowire (without SDS) to the nanorod (with SDS). Strong yellow-orange emissions could be obtained in Sm3+ and Eu3+ ions codoped GdPO4 phosphors under ultraviolet light irradiation. Moreover, the energy transfer mechanism from Sm3+ to Eu3+ has been studied and proved to be a dipole-dipole interaction mechanism. These results show this yellow-orange-emitting phosphors material may have potential applications in field-emission displays.
