Vacuum-Referred Binding Energies of Bismuth and Lanthanide Levels in LiTaO₃ Perovskite: Toward Designing Energy Storage Phosphor for Anti-Counterfeiting, X-Ray Imaging, and Mechanoluminescence

Discovering UV-light or X-ray charged afterglow and storage phosphors with high charge carrier storage capacity remains challenging. Herein, a method is proposed by combining vacuum referred binding energy (VRBE) diagram construction and optimization of dopants’ concentration and compound synthesis. The refined chemical shift model, optical...

LiTaO₃:Bi³⁺,Tb³⁺,Ga³⁺,Ge⁴⁺: A Smart Perovskite with High Charge Carrier Storage Capacity for X-Ray Imaging, Stress Sensing, and Non-Real-Time Recording

Developing X-ray or UV-light charged storage and mechanoluminescence (ML) materials with high charge carrier storage capacity is challenging. Such materials have promising utilization in developing new applications, for example, in flexible X-ray imaging, stress sensing, or non-real-time recording.

The Bi³⁺ 6s and 6p electron binding energies in relation to the chemical environment of inorganic compounds

This paper provides an overview and interpretation of the spectroscopic data of the Bi³⁺ activator ion in 117 different inorganic compounds. The energies of the metal-to-metal charge transfer and the interconfigurational transitions of Bi³⁺ were collected from the archival literature. Using these energies, in combination...

Utilizing high-energy γ-photons for high-resolution ²¹³Bi SPECT in mice

The combined α-, γ-, and x-ray emitter ²¹³Bi (half-life, 46 min) is promising for radionuclide therapy. SPECT imaging of ²¹³Bi is challenging, because most emitted photons have a much higher energy (440 keV) than common in SPECT. We assessed ²¹³Bi imaging capabilities of the Versatile Emission Computed...
