Crystalline Organic Materials Toward Laser Application

Abstract

Although optically pumped organic laser has been observed and investigated intensively in the past few decades, realization of electrically pumped organic laser is still a great challenge. Toward this challenge, efforts from both material science and device engineering research fields have been and will be made by scientists. In this chapter, the relationship between molecular stacking and optoelectronic properties in crystalline organic materials is discussed in detail first. Based on the deep understanding of the structure-property relationship, the recent progresses on highly efficient electroluminescent (EL) materials and light-emitting field-effect transistors are reviewed respectively. At last, a perspective is given on further development of organic materials and devices for laser application.
