The Humbert-Haze Relationship

The Humbert-Haze relationship describes how two different light-matter interactions, called excitons, combine within certain materials like organic semiconductors. It explains how these excitons influence each other’s energy states and how they couple to light, affecting the material's optical properties. This relationship helps scientists understand and predict how these materials absorb, emit, or manipulate light, which is essential for developing advanced optoelectronic devices such as organic LEDs and solar cells. In essence, it’s a framework for analyzing the interplay between electronic excitations and their optical behavior in complex molecular systems.
