6 FAQs about [Energy storage and luminescence principle]
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.
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.
