Light‐induced heat has a non‐negligible role in photocatalytic reactions. However, it is still challenging to design highly efficient catalysts that can make use of light and thermal energy synergistically. Herein, the study proposes a plasma super‐photothermal S‐scheme heterojunction core‐shell nanoreactor based on manipulation of the driving factors, which consists of α‐Fe2O3 encapsulated by g‐C...
In this paper, the multisignal (different emissions/colours) temperature sensing of NaYF4:Eu3+ nanoparticles is investigated, which is based on fluorescence intensity ratios (FIRs) between 5D0→7FJ (J=1‐4) and 5D1→7FJ’ emissions. The 5D1→7FJ’ (J'=0‐2) emissions can be clearly observed due to the low photon energy of NaYF4. Based on the FIRs between different 5D0→7FJ and 5D1→7FJ’ emissions, higher absolute/relative...
A facile hydrothermal method is used to prepare Pt‐functionalized nanoporous TiO2 nanoparticles. These are used as gas‐sensing material in sensors, fabricated according to the indirect heating method. Gas‐sensing performance of the sensors is investigated by testing their gas response to acetone, which exhibits favorable selectivity, good gas response value, fast response/recovery time, low detection...
