Recently,halide perovskite materials have become an exciting topic of research mainly due to their outstanding photovoltaic performance with the highest efficiency up to 22.1% at present.The nanocrystals (NCs) of these perovskites show quantum size effect,tunable bandgap,and excellent photoluminescence quantum yield (PLQY) in specific cases.Perovskite NCs have hence displayed great potentials in a broad range of applications,such as solar cells,light-emitting devices (LEDs),photodetectors,and lasers.In this review,we summarized the recent progress on the synthesis,optoelectronic properties and applications of the nanostructures of these halide perovskite materials,including hybrid organic-inorganic perovskites,pure inorganic perovskite,and perovskite-derived NCs.We have aIso provided a critical outlook into the challenges ahead.

To construct efficient low band gap polymers,increasing the Quinone structure of the polymer backbone could be one desirable strategy.In this work,two D-Q-A-Q polymers P1 and P2 were designed and synthesized with thiophenopyrrole diketone (TPD) and benzot
To satisfy the rapid development of gas-involving electrocatalysis (O2,CO2,N2,etc.),nanostructured electrocatalysts with favorably regulated electronic structure and surface nanostructures are urgently required.Herein,we highlighted a core-branch hydroxys
MXene has shown distinctive advantages as anode materials of lithium-ion batteries.However,local surface chemistry,which was confirmed that can block ion transfer and limit redox reaction,has a significant effect on electrochemical performance.Herein,anne
Single crystal anatase TiO2 nanospindles (NSs) with highly exposed {101 facets were synthesized and employed as electron transport materials (ETMs) in perovskite solar cells (PSCs).Time-resolved photoIuminescence (TRPL) spectra revealed that the TiO2 NSs
Lithium (Li) metal with an ultrahigh specific theoretical capacity and the lowest reduction potential is strongly considered as a promising anode for high-energy-density batteries.However,uncontrolled lithium dendrites and infinite volume change during re
