摘要
Abstract
The fluorescence of Rhodamine B was quenched due to the surface energy transfer from Rhodamine B to silica supported gold nanoparticle surface .The Stern-Volmer quenching constant of the gold nanoparticles was 4.3 ×103 L/mol in this system .While , the fluorescence of Rhodamine B recovered after the addition of thiols due to the strong affinity of thiol to gold nanoparticles which obstructed the energy transfer between Rhodamine B and gold nanoparticles.As the unique response of Rhodamine B-Au-SiO2 system to thiols, it provides a simple analytical method for the detection of thiols .Moreover, Au-SiO2 becomes a recyclable probe because of the stabilization of silica support .关键词
