"Nephelauxetic" Natural Recordings by Native Speakers
Nephelauxetic refers to a property of certain optical materials that exhibit a negative change in refractive index when exposed to intense light, particularly in the ultraviolet or visible spectrum. This means that the material's refractive index decreases as the light intensity increases. This phenomenon is also known as "nephelauxetic effect" or "nephelauxetic change".
