Thermal quenching for fluorescence in colquiriite crystal

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 CaLiAlF6

TQF(Thermal quenching for fluorescence) reduces the fluorescence quantum efficiency as temperature increases

- Dynamic quenching: excited states of fluorescent material losing energy through collision with other molecules(quenchers). Temperature increases, the kinetic energy of the molecules also increases, leading to more frequent collisions.

- Static quenching: fluorescent material forms a complex with a quencher in the ground state, which inhibits fluorescence emission. This complex does not emit fluorescence and may have its own absorption spectrum.
