| Abstract: | Fluorescent hybrid nanospheres of SiO2/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,TG,PL and TEM.The results showed that Rhodamine B was linked to SiO2 via chemical bond,the diameter of hybrid nanospheres was about 200 nm.The nanospheres showed better heat resistance and UV light resistance th... |
