Uv energy storage lamp

Can UV light be used for solar energy storage?

Thus, in most energy storage systems, UV light is used for illumination. To use the solar energy more efficiently, a few visible light harvesting materials 5, 15 have been investigated recently. However, the absorption of these materials in visible spectrum remains insufficient, due to the absorption threshold of them.

Which light harvesting materials are used in solar energy storage systems?

Whereas the variety of the material system has been rapidly developed, the most frequently used light harvesting material is still TiO 2. Thus, in most energy storage systems, UV light is used for illumination. To use the solar energy more efficiently, a few visible light harvesting materials 5, 15 have been investigated recently.

What is a deep-trap ultraviolet storage phosphor?

In this work, we report a novel deep-trap ultraviolet storage phosphor ScBO 3:Bi 3+, which shows a remarkably narrowband ultraviolet emission centered at 299 nm with an unprecedented FWHM of approximately 0.21 eV, along with exceptional capabilities for storing X-ray energy.

What is the difference between light harvesting materials and energy storage materials?

Light harvesting materials are materials capable of absorbing light to generate electron-hole pairs. Energy storage materials are materials in charge of trapping and saving the electrons or holes transferred from light harvesting centers during illumination and releasing them in dark.

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.

Can lcbcs store a phase transition energy under UV light?

The LCBCs can also simultaneously store both the isomerization energy and the phase transition energy from the liquid crystalline phase to the isotropic phase under UV light. The prepared composite film (sPEO + PEO-b-PAzo) achieved an energy density of 210.3 J·g −1, with the released energy comprising all four components, as shown in Figure 12c–f.
