Source: Leica Microsystems Understanding Luminescence: A Comprehensive Guide Understanding Luminescence: A Comprehensive Guide Luminescence is a fascinating phenomenon where substances emit light without the need for high temperatures. Unlike thermal radiation, which is light emitted due to heat, luminescence occurs at much lower temperatures, earning it the nickname “cold light.” This unique property makes luminescence
