摘　　要：碳点因其具有较好的光学性质和良好的生物相容性等而在生物化学领域得到广泛应用,但通常受到其短波长发射光的局限.本文基于碳点与meso-四(对-磺酸苯基)卟啉之间的荧光共振能量转移,构建了长波长发射体系,研究了能量供体碳点与能量受体meso-四(对-磺酸苯基)卟啉的浓度、pH、盐度及黏度对二者能量转移效率的影响.Owing to the distinct optical properties, excellent biocompatibility and so on, carbon dots have been widely applied in biologic and chemical field, but the short wavelength emission always limits it. In this contribution, based on the fluorescence resonance energy transfer between carbon dots and meso-tetra-（p-sulfonatophenyl） porphyrin （TPPS4）, we establish a system of long wavelength emission and investigate how the concentration of carbon dots and TPPS4, pH, salinity, and viscosity influence the efficiency of the energy transfer between carbon dots and TPPS4.
