Solvothermal Method Preparation of Nano Y₂O₂S:Eu ³⁺ and Research of Luminescence Property

Abstract:

The nano Y²O²S:Eu ³⁺0.01 were prepared with solvohtermal method. Using ethylenediamine as solvent, at 220°C for 12h , we get the best sample. The effect of various reaction times, surfactant in reaction on nano-particle size of the products were investigated in detail. Using the Laser granularity cryoscopy（rise 2008）to display the products size, the result shows that the sample size about 45nm, and the SEM shows that the morphology are nano wires. The emission spectrum shows that the strongest peak is located at 625nm, which attributed toEu ³⁺ ions’⁵D0^-7 F₂ transition.
