In principle, a storage phosphor is a material analogous to an inorganic scintillator, with the difference that in a storage phosphor, a significant part of the energy … WebDue to the unique narrow-band red emission and broadband blue light excitation, as well as milder synthesis conditions, Mn4+ ion activated fluoride red phosphors show great promise for white light emitting diode (W-LED) applications. However, as the Mn4+ emission belongs to a spin-forbidden transition (2Eg → 4A2), it is a fundamental challenge to synthesize …
Phosphorescence is a type of photoluminescence related to fluorescence. When exposed to light (radiation) of a shorter wavelength, a phosphorescent substance will glow, absorbing the light and reemitting it at a longer wavelength. Unlike fluorescence, a phosphorescent material does not immediately reemit the radiation it absorbs. Instead, a phosphorescent material absorbs some of t…
