摘　　要：搭建了结构紧凑简单、性能稳定、成本低廉的表面等离子体耦合荧光(SPCE)小型装置。通过对罗丹明S101样品荧光信号角度分布和偏振性的测试,分析了该小型装置的仪器性能,结果令人满意。该装置完全能够满足SPCE一般的测试要求,可望推广使用。A miniature spectrofluorimeter for surface plasmon coupled emission （SPCE） technique has been developed using a laser pointer as the light source. Here we investigate its performance by measuring SPCE from sulforhodamine 101 doped PVA. The fluorescence signal on the prism side emitted at a sharply directional angle of 47° and was definitely p-polarized with different wavelengths appearing at different angles. It is demonstrated that this laboratory-construc- ted speetrofluorimeter is able to meet the general test requirements of SPCE technique. Compared with the previously reported devices,our speetrofluorimeter has many advantages such as simple, stable performance and low cost.
