电致发光和电子雪崩是用于暗物质搜索和中微子检测的两相氩和氙探测器中使用的物理效应，用于直接放大低温惰性气体介质中的初级电离信号。我们回顾了这种光和电荷信号放大的概念，包括它们在气相和液相中的组合。解释了两相探测器中电致发光和电子雪崩物理学的令人困惑的方面，并描述了基于这些效应的探测技术。
Electroluminescence and electron avalanching are the physical effects used in two-phase argon and xenon detectors for dark matter searches and neutrino detection, to amplify the primary ionization signal directly in cryogenic noble-gas media. We review the concepts of such light and charge signal amplification, including a combination thereof, both in the gas and in the liquid phase. Puzzling aspects of the physics of electroluminescence and electron avalanching in two-phase detectors are explained, and detection techniques based on these effects are described.
