采用 8 2 MHz、51 4.5nm的 Ar+激励光源 ,通过我们所建立的 CCD皮秒扫描成象发射光谱装置分别对 PS 颗粒 ,内周天线 CP43、CP47,外周天线 LHC 四种样品的发射光谱进行扫描成象 ,直接、快速地获得了它们的发射光谱曲线 .通过分析认为 ,PS 的发射荧光很大程度上是由内周天线 CP47中的叶绿素 a所发出的 The emission spectra of PS particles, CP43, CP47, LHC, and LHC were scanned by the Picosecond Scanning Imaging Emission Spectrometer with 8 2 MHz and 51 4.5 nm Ar + excitation light source. Image, directly and quickly obtain their emission spectrum curve.It is considered by analysis that the emission fluorescence of PS is largely caused by the chlorophyll a in the internal antenna CP47
