Abstract

The embodiment of the invention discloses real-time observation and evaluation equipment for charge behaviors based on electroluminescence. The equipment comprises a darkroom, a vacuum system, an electrode system, a monochrometer, a photoelectric calculator, a PD sensor, a high-voltage power supply, an oscilloscope, a computer, a sample room and a silica glass observation window. By externally applying alternating and direct current voltages, a material is stimulated to generate electroluminescence, the processes of injection, extraction, compounding and the like of charge carriers on the surface or in the material can be researched by collecting electroluminescence signal strength and spectral information, and the researches help disclose an electrical aging mechanism of a dielectric material, and an important measure can be provided for the anti-aging research of novel materials.

Description

technical field [0001] The invention relates to the field of electroluminescence testing, in particular to a real-time observation and evaluation device for charge behavior based on electroluminescence. Background technique [0002] Electroluminescence (Electroluminescence-EL) is a phenomenon in which a polymer is directly converted into light energy during its performance or internal electron transfer process after being excited by electricity. Electroluminescence is often used as an important tool to study the surface or internal trap properties of materials, charge storage capacity and transport properties, as well as structural transformation and molecular motion of polymers. Electroluminescence consists of three main processes: excitation, energy transfer, and composite luminescence. When the material is under a certain electric field distribution, the velocity and energy distribution of the carriers inside the material will change, including: carrier injection (electr...
