nanoparticles were synthesized by a hydrothermal method. The studies of the powder X-ray diffraction

transmission electron microscopy

high-resolution transmission electron microscopy

and energy-dispersive X-ray spectroscopy show that the -NaGd

nanoparticles crystallize in the shape of hexagonal morphology and ellipsoidal sphere with an average size of about 23 nm. Room-temperature bright white light emission in Yb

ions doped -NaGdF

nanoparticles was observed in an upconversion process under the excitation of single-wavelength diode laser of 980 nm. The white light consists of the blue

green

and red upconversion emissions

which correspond to the transitions

of Tm

and

of Ho

ions

respectively. By the spectral positions at 476

542

and 650 nm we have the white-light coordinates

=0.271 7 and

=0.267 3.
