:Nd

nanophosphors was prepared with a solvothermal method using glycol-water mixed solution as a solvent

then calcined at 800℃ for 1 h. The samples were tested with X-ray diffraction

transmission electron microscope

emission and excitation spectrum. Uniform Gd

MoO

:Nd

nano-spher with good dispersity and efficient near infrared emission can be achieved at a reaction temperature as low as 800℃ and pH value of 1.5. The optimized Nd

doping mole fraction is 0.03. The ratio of water to ethylene glycol is 1:1. The particle is promising in the application of fluorescence immunoassay.
