一、引言近年来,荧光寿命、能量或动量的弛豫衰减过程和时间分辨率光谱等测最技术对物理、化学、生物等学科在光激发诱导过程的了解作出了很大的贡献。设在英国 Heriot-Watt 大学内的爱丁堡仪器公司所生产的199型荧光光谱仪是实现上述技术要求并能够进行常规应用的理想仪器。该产品是由英国
I. Introduction In recent years, fluorescence lifetime, energy or momentum relaxation decay process and time-resolution spectroscopy and other measurement techniques for physical, chemical, biological and other disciplines in the light-induced induction process has made a significant contribution. The Model 199 fluorescence spectrometer from Edinburgh Instruments, located at the Heriot-Watt University in England, is the ideal instrument for these technical requirements and for routine applications. The product is made in the UK
