An Introduction to Steady-State and Time-Resolved Photoluminescence

Abstract

In this chapter, we present the fundamentals of photoluminescence, including a phenomenological standpoint for approaching important concepts such as photoluminescence lifetime, emission quantum yield, and relaxation rates. The relation between photoluminescence and other photophysical processes, namely, intersystem crossing and internal conversion is also thoroughly discussed. Experimental guidelines for both steady-state and time-resolved photoluminescence are also addressed. The importance of photoluminescence in the investigation of materials for technological applications, for example, light-emitting devices is highlighted.
