Photoluminescence: Principles, Structure, and Applications

摘要

Photoluminescence, a powerful and break-less analysis technology, can reveal the band structure and the carrier transportation behaviors in a material. Moreover, the doping type, band gap, composition, etc. of the bulk material or the size, path of carrier transportation, lifetime, etc. of the nano-material will be shown in the photoluminescence spectrum. So the photoluminescence could be a judgment of the material quality and be a key technology of the development of nano-technology. This paper emphasized to introduce the principles, structure, and applications of the photoluminescence, photoluminescence excitation, confocal image with micro-PL, and time-resolved photoluminescence systems.
