摘要

在甲苯存在下的反相微乳液体系中

将-缩水甘油醚氧丙基三甲氧基硅烷(KH560)与罗丹明B进行预反应;再与正硅酸乙酯(TEOS)经原位溶胶-凝胶反应

制备SiO

/罗丹明B荧光杂化纳米微球。通过FTIR、UV-Vis、TEM、TG和光致发光谱对杂化纳米微球进行了表征。结果表明:罗丹明B与KH560间通过酯基形成化学键合

杂化纳米微球的直径约为200 nm

其耐热稳定性和耐紫外光稳定性优于罗丹明B

荧光强度约为罗丹明B的4倍。

Abstract

Fluorescent hybrid nanospheres of SiO

/Rhodamine B were prepared. Firstly

3-glycidyloxypropyl trimethoxysilane (KH560) reacted with Rhodamine B in water-in-oil microemulsion

and then they reacted with TEOS in the microemulsion by sol-gel in-situ. The hybrid nanospheres were characterized by FTIR

UV-Vis

PL and TEM. The results showed that Rhodamine B was linked to SiO

via chemical bond

the diameter of hybrid nanospheres was about 200 nm. The nanospheres showed better heat resistance and UV light resistance than Rhodamine B. The PL intensity of the hybrid nanospheres was about 4 times of Rhodamine B.
