Phosphor energy storage wavelength

Which phosphor is used for optical data storage based on photostimulated luminescence?

Wu, H. et al. Optical storage and operation based on photostimulated luminescence. Nano Energy 90, 106546 (2021). Zhang, J. M. et al. Giant enhancement of a long afterglow and optically stimulated luminescence phosphor BaCaSiO 4: Eu 2+ via Pr 3+ codoping for optical data storage. J. Lumin. 263, 119971 (2023).

What is a deep-trap ultraviolet storage phosphor?

Here, we report an appealing deep-trap ultraviolet storage phosphor, ScBO 3:Bi 3+, which exhibits an ultra-narrowband light emission centered at 299 nm with a full width at half maximum (FWHM) of 0.21 eV and excellent X-ray energy storage capabilities.

What are storage phosphors used for?

Storage phosphors as a kind of information storage materials have been widely used in computed radiography (CR) based on X -ray storage phosphor plate [ 1], dosimetry of X -rays, γ -rays or electrons [ 2] and optical data storage [3 ], etc.

What are the optical properties of a phosphor?

The optical properties of a phosphor stem from crystal–chemical interactions between a crystalline host material, often an oxide, (oxy-)halide, (oxy-)sulfide or (oxy-)nitride, and a rare-earth or transition metal activator ion, which has been partially substituted within the host structure and acts as a luminescence centre 3, 6, 7 (Fig. 1a).

Which storage phosphor is best?

Recently, Lyu and Dorenbos et al. reported an excellent storage phosphor, Li (Y/Lu)SiO 4 :Ce 3+ ,Sm 3+, which is superior to the commercial storage phosphorescent materials in terms of carrier storage capacity, negligible attenuation of information storage and low hygroscopic property [ , , ].

Do storage phosphors emit in the deep ultraviolet region?

In this case, storage phosphors emitting in the deep ultraviolet region are preferred, considering that deep ultraviolet radiation encompassing the light spectrum over 200–300 nm, does not overlap with room light and can be detected with zero background noise in a bright indoor-lighting environment 34, 35, 36, 37, 38.
