High photoinduced charge-carrier-separation efficiency plays a crucial factor in determining the photocatalytic activities of photocatalysts, and it remains challenging to steer charge separation an accurate manner. Herein, we address this important challenge by growing Co2P cocatalyst onto edges black phosphorus (BP) nanosheets craft Co–P bonds Co2P/BP photocatalyst. As demonstrated photocurrent measurement first-principle calculation, acting faciliate atomic-level charge-flow steering can...
To date, non-contact luminescence thermometry methods based on fluorescence intensity ratio (FIR) technology have been studied extensively. However, designing phosphors with high relative sensitivity (Sr) has become a research hotspot. In this work, Eu3+ single-doped Ca2Sb2O7:Eu3+ Sr value for dual-emitting-center are developed and proposed. The anti-thermal quenching behavior of originating from the energy transfer (ET) host → is found proved in designed phosphors. Interestingly, adjustable...
Abstract Fe 3+ ‐doped MgGa 2 O 4 (MGO: ) spinel‐type near‐infrared (NIR) phosphor with non‐toxicity, outstanding thermal stability, and tunable emission has recently gained great concern owing to its wide applications. Nevertheless, the existence of detrimental defects in host forbidden d‐d transitions lead unsatisfactory luminescence efficiency, limiting commercial application.

Luminescent thermometers provide a non-contact method of probing temperature with high sensitivity and response speed at the nanoscale. Synergistic photoluminescence from different activators can realize for luminescent by finely selecting ions specific crystallographic sites. Herein, more temperature-sensitive Mn4+ less-sensitive Eu3+ (or Sm3+) are co-doped into Ca2GdSbO6 matrix to form an effective thermometer, where occupy Sb5+ Gd3+ sites, respectively. The co-doping or Sm3+ leads lattice...
