Sonodynamic therapy is a noninvasive treatment method that generates reactive oxygen species (ROS) triggered by ultrasound, to achieve oxidative damage tumors. However, methods are required improve the efficiency of ROS generation and continuous damage. A ternary heterojunction sonosensitizer composed Bi@BiO2-x @Bi2 S3 -PEG (BOS) thermal injury-assisted sonodynamic for tumors prepared. The vacancy in BOS can capture hot electrons promotes separation carriers on bismuth surface. local...
Thermal quenching has always been one of the most difficult issues in creating high-quality phosphor conversion light-emitting diodes (pc-LED), and a family strategies are urgently needed to improve luminescence performance phosphors at high temperatures. In this contribution, novel B'-site substitution CaLaMgSbxTa1-xO6:Bi3+ was constructed using an ion strategy matrix with green activator Bi3+ double perovskite material. When Sb5+ replaces Ta5+, surprising increase intensity occurs thermal...
Bi3+-related metal-to-metal charge transfer (MMCT) transition phosphors are expected to become a new class of solid-state luminescent materials due their unique broadband long-wavelength emission; however, the main obstacle application is thermal quenching effect. In this study, one novel mechanism Bi3+-MMCT luminescence proposed by introducing electron-transfer potential energy (ΔET). Y0.99V1-xPxO4:0.01Bi3+ (YV1-xPxO4:Bi3+) used as model; when band gap activator Bi3+ increases from 3.44...
Thermal quenching performance is a huge challenge in the application of phosphor materials. In this paper, relationship between energy gap luminescent ions and thermal activation (ΔE) discussed from angle energy-level splitting for first time. When proportion coordination cations (Nb–Ta) matrix adjusted, dissimilarity bond lengths angles two crystal configurations (NbO6/TaO6) makes electron cloud expand, decrease atomic orbital overlap reduces covalency, nephelauxetic effect enlarges length...
Pr3+-related intervalence charge transfer (IVCT) bands are a research hotspot owing to their amelioration in the luminescence thermal quenching of Pr3+-activated phosphors. Here, typical IVCT band displacement strategy via topological chemical scheme is reported optimize performance praseodymium-doped niobo-tantalate. The substitution Ta5+ ions for Nb5+ reduces valence-weighted average cation optical electronegativity and increases bond lengths activator (Pr3+) ligand cations (Nb5+ Ta5+)...

The utilization of phosphor materials has always been a significant challenge in terms improving thermal quenching performance. In this work, the performance tuning mechanism which establishes band gap and correlation patterns is proposed. crystal field splitting energy Dq was decreased by changing surrounding lattice environment Bi3+ through solid solution replacement, activation ΔE tuned from 0.117 eV to 0.182 accordingly. At 423 K, luminous intensity increases 0.101 0.396 preliminary at...
