ETU(Energy transfer upconversion)- Energy is transferred from one laser-active ion to another, leading to the excitation of the latter to a higher energy state than what would be achieved through simple photon absorption. - Primarily facilitated by dipole-dipole interactions b/w ions within the crystal lattie. ETU can significantly influence the optical properties and fluorescence behavior of th..

Colquiriite crystals: rare white mineral with the chemical formula CaLiAlF6- mineral formula for Colquiriite crystal: contains aluminum, calcium, fluorine, and lithium. Its empirical formula is CaLiAlF6TQF(Thermal quenching for fluorescence) reduces the fluorescence quantum efficiency as temperature increases - Dynamic quenching: excited states of fluorescent material losing energy through colli..
