β‐In 2 S 3 is a natural defective III–VI semiconductor attracting considerable interests but lack of efficient method for its 2D form fabrication. Here, the first time, this paper reports controlled synthesis ultrathin flakes via facile space‐confined chemical vapor deposition method. The defects in crystals, clearly revealed by optical spectra and optoelectronic measurement, strongly modulate (opto)‐electronic as‐fabricated render it broad detection range from visible to near‐infrared....
The remarkable properties of graphene have inspired great research interest in two-dimensional layered materials (2DLMs) with novel electronic and optical attributes. As a class graphene-like 2DLMs, ultrathin group IIIA metal chalcogenides (GIIIAMCs, = In, Ga; chalcogen S, Se, Te) shown potential electronics optoelectronics. In this review, we first introduce the crystal structures their unique advantages specific applications. Then, summarize progress fabrication GIIIAMCs framework top-down...

The layered Bi 2 Se 3 with a narrow band gap 0.3 eV regarded as promising candidate toward high‐performance terahertz to infrared However, the controllable synthesis large‐size ultrathin flakes remains challenge owing complex nucleation process telecommunication photodetectors based on are rarely reported. Here, large size (submillimeter:...
Abstract Second harmonic generation (SHG) as an essential nonlinear optical effect, has gradually shifted its research trend toward the integration and miniaturization of photonic optoelectronic on‐chip devices in recent years. 2D layered materials (2DLMs) open up a new paradigm optics due to their large second‐order susceptibility, atomically thin structure, perfect phase‐matching. However, 2DLMs are facing bottleneck weak SHG conversion efficiency limit caused by short light–matter...
Double-shell-structured β-NaYF4:Yb3+,Tm3+/Er3+@SiO2@TiO2 upconversion photocatalysts have been successfully synthesized by a simple hydrothermal method. It is found that the double-shell-structured photocatalyst consists of uniform β-NaYF4:Yb3+,Tm3+/Er3+ nanocrystals, SiO2 as media shell, and anatase TiO2 nanocrystals exposed with high-reactive {001} facets outer shell. The shell modified to absorb both UV visible light in order make sufficient use upconverted from for photocatalysis....
Abstract Due to the predicted excellent electronic properties superior group VIB (Mo and W) transition metal dichalcogenides (TMDs), IVB TMDs have enormous potential in nanoelectronics.

Moreover, effect key growth parameters including dimensions confined space deposition temperature on behavior products systematically studied. Typical as‐synthesized a...
Better tissue penetration and lower overheating problems mean 808 nm near-infrared laser excited upconversion nanoparticles (UCNPs) have potential in bioapplications. Dumbbell-like structured NaYF4:Yb/Er@NaNdF4:Yb are fabricated this work applied photodynamic therapy (PDT). The epitaxial growth along the c axis attributed to large structure mismatch of NaNdF4versus NaYF4 has been demonstrated play a key role dumbbell structure. Due better space separation structure, energy back-transfer from...

As a novel layered indium selenide (InSe) semiconductor has been attracting considerable interest in the field of modern (opto)-electronics. Despite current progress, synthesis ultrathin InSe nanoflakes still poses quite challenge, due to its universal co-existing varied stoichiometric compounds.
