A glass scintillator with high spatial resolution of 20 lp mm −1 and refreshable X-ray imaging is designed. The practical tests also reveal the great potential for applications in imaging.
A novel broad-band emission glass scintillator is designed under redox control with greatly enhanced PL (7.2 times) and XEL (1.8 performances.
Abstract Far‐red (FR) and near‐infrared (NIR) spectroscopy technologies have attracted extensive attention. How to obtain luminescent materials suitable FR‐NIR phosphor‐converted light‐emitting diodes (pc‐LEDs) is a crucial challenge. Herein, Si 3 N 4 ‐substitution strategy employed regulate the luminescence of Gd Ga 5 O 12 :Cr 3+ (GGG:Cr ) phosphors. The bandwidth GGG:Cr 95 nm, then it broadened 116 nm due ‐substitution. Furthermore, at 423 K thermal stability enhanced 98.7% that room...
Developing high-performance broadband near-infrared (NIR) phosphors for NIR phosphor-converted light-emitting diodes is still a challenge. Co-doping an effective strategy enhancing the performance of phosphors. Herein, we explore phosphor by co-doping Yb3+ into LiScSi2O6:Cr3+ (LSS:Cr3+). Under 468 nm excitation, LSS:Cr3+,Yb3+ exhibits broad emission from 700 to 1100 nm. Due efficient energy transfer Cr3+ Yb3+, maximum bandwidth reaches 219 nm, broader than that LSS:Cr3+ (170 nm). The...
Far-red (FR) photosensitive pigment (PFR) is vital for plant photomorphogenesis. Phosphor-converted (pc) LEDs are the next-generation FR light devices. How to obtain FR-emitting phosphors with a good quantum efficiency, suitable photoluminescence and high thermal stability still difficult. Herein, we optimize Y3Ga5O12:Cr3+ phosphor, which has an emission peak at 711 nm full width half maximum of 74 nm, closing PFR absorption band. By adopting solid-state sintering technology, internal...
