由光引起物质电学性质变化的现象,已为人们所熟知,如光电导现象,光生伏特效应等。利用这些现象可以用光来控制电的变化。但是反过来,利用较微弱的电来直接控制光的变化,则是在场致发光现象被发现后才有实际意义。随着固体电子学的发展和固体电子学材料性能的日益完善,人们才开始系统深入地探讨光与电的各种现象间的相互关系,并从中发展
The phenomenon of changes in the electrical properties of a substance caused by light has been well known, such as photoconductivity, photovoltaic effect and the like. Use these phenomena can use light to control the change of electricity. However, in turn, the use of weaker electricity to directly control light changes is of practical significance after electroluminescence has been detected. With the development of solid-state electronics and the improvement of the performance of solid-state electronic materials, people began to systematically and deeply explore the interrelationships between various phenomena of light and electricity and develop from them
