What is luminescence in physics?

M. G. Brik shortly defined the phenomenon of luminescence as a method of conversion of excitation energy (which can be supplied to a luminescent object in various ways via external sources) into emitted light energy .

What is persistence luminescence?

Persistent luminescence is a process where the material emits light in the visible range appreciably for hours even after the irradiation source has been waived off. The storage of the irradiation energy by the traps is supposed to be responsible for long decay time of persistence luminescence.

How do luminescent materials work?

Luminescent materials are capable of transforming certain types of energy into electromagnetic radiation, which means that in response to a specific stimulus, these materials emit light typically within the ultraviolet (UV) to the infrared (IR) spectral region [1, 2].

What are optical stimulated luminescence (OSL) materials?

Optically stimulated luminescence (OSL) materials enable energy storage and then energy conversion to light upon photostimulation, with applications spanning from radiation dosimetry, optical data storage and security, environmental monitoring, biomedicine, clinical diagnostic, to archaeology and geology.

What are the excitation and emission processes governing the luminescence phenomenon?

In this section, the excitation and emission processes governing the luminescence phenomenon and the transfer of excitation energy within a given phosphor system will be introduced. The event of absorption occurs when the energy of incident light matches well with the energy gap of two energy states of the optical materials.

What is luminescence & how does it work?

Luminescence is classically defined as relaxation of species from the excited state followed by spontaneous light emission. The material is activated or charged by blue/UV content of solar radiation during regular condition. In extreme dark conditions, the energy is released as afterglow.
