【Abstract】 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-constructed spectrofluorimeter is able to meet the general test requirements of SPCE technique.Compared with the previously reported devices,our spectrofluorimeter has many advantages such as simple, stable performance and low cost.更多还原
