Persistent Luminescent Materials

Abstract

Persistent luminescent materials have become an important class of multi-functional materials and have a broad application in many fields. The persistent luminescent materials have been mainly used as luminous materials. Besides, as for the photocatalysis, the persistent luminescent materials act as the light source for the photocatalysis in dark environment; as for sensing, the persistent luminescent materials use their temperature change and mechanoluminescence features to measure the environment temperature and pressure; the application of the persistent luminescent materials in biomedical study lies in the luminescent marker, tumor diagnostics and analysis, as well as photodynamic therapy of cancer; as for the application in solar energy, the persistent luminescent materials can be used in photoelectron nano-devices, fiber amplifier, and photovoltaic materials; the persistent luminescent materials can also be used in agriculture, as the light source for plant growth, and enhance the photosynthesis of the plants. Combining the published work with our research, this chapter will include: the basic concepts and history of persistent luminescent materials, the classification of the persistent luminescent materials, the luminescent mechanism and model, and the basic methods and conditions to realize the persistent luminescence, the applications of the persistent luminescent materials, and the prospects of the persistent luminescent materials in the end.
