Wide Range X-Ray to Infrared Photon Detection and Energy Storage in LiTaO₃:Bi³⁺,Dy³⁺ Perovskite

It is challenging to obtain a material that can detect photons ranging from X-rays to infrared light. Such materials have promising use to develop advanced applications like in information storage, anticounterfeiting, or X-ray imaging. This article reports on such a material; LiTaO₃:xBi³⁺,yDy³⁺ perovskite...

VUV-UV-vis photoluminescence, X-ray radioluminescence and energy transfer dynamics of Ce³⁺ and Eu²⁺ in Sr₂MgSi₂O₇

Ce³⁺ and Eu²⁺ doped and Ce³⁺-Eu²⁺ co-doped Sr₂MgSi₂O₇ phosphors are prepared via a high-temperature solid-state reaction technique. The synchrotron radiation vacuum ultraviolet-ultraviolet (VUV-UV) excitation and ultraviolet-visible (UV-vis) emission spectra of...

Unraveling electron liberation from Bi²⁺ for designing Bi³⁺-based afterglow phosphor for anti-counterfeiting and flexible X-ray imaging

It is challenging to rational design persistent luminescence and storage phosphors with high storage capacity of electrons and holes after X-ray charging. Such phosphors have potential applications in anti-counterfeiting and X-ray imaging. Here we have combined vacuum referred binding energy diagram (VRBE) construction, photoluminescence...
