摘要

用溶剂热法制备了BaSn(OH)

前驱体

经煅烧后

得到BaSnO

纳米粉末。用XRD、TEM、纳米粒度仪、紫外-可见-近红外分光光度计、光纤光谱仪等对样品的结构、形貌和性能进行了表征。BaSnO

纳米粒子为粒径约为30~50nm的球形颗粒

具有良好的分散性

也具有很好的近红外发光性能

其最大激发和发射波长分别位于385nm和895nm。与高温固相法得到的样品相比

该方法所得纳米BaSnO

样品的近红外发光强度提高近10倍

样品结晶程度的提高和缺陷的减少可能是样品近红外发光强度提高的主要原因。

Abstract

BaSnO

nano-phosphors were prepared by solvothermal method using glycol-water mixed solution as a solvent

followed by calcinations at different temperature. The as-synthesized samples were characterized by X-ray diffraction (XRD)

transmission electron microscopy (TEM)

the nano-particle size analyzer

excitation and emission spectra. The nano-powders are sphere with sizes of 30~50 nm. Good dispersity can be achieved even after the sample was calcined. Efficient near-infrared fluorescence with emission peak of 895 nm was observed under the excitation of 385 nm. Comparing with the sample prepared by solid state reaction

the emission intensities increase about ten folds. The degree of crystallization is found to be the main fact of the near-infrared fluorescence of BaSnO

nanoparticles.
