Ag2O-decorated flower-like ZnO composites were fabricated through a chemical precipitation process. X-ray diffraction analysis confirms the co-existence of cubic Ag2O and wurtzite phases. Scanning electron microscopy images reveal nanoparticles located on rough surface flowers. The photocatalytic activities with various mole ratios evaluated by degradation methyl orange (MO) under ultraviolet irradiation, which that composite shows superior activity to pure Ag2O. improvement can be ascribed...
In this paper, we report a large lateral photovoltaic effect (LPE) with ultrafast relaxation time in SnSe/p-Si junctions. The LPE shows linear dependence on the position of laser spot, and sensitivity is as high 250 mV mm−1. optical response are about 100 ns 2 μs, respectively. current-voltage curve surface SnSe film indicates formation an inversion layer at interface. Our results clearly suggest that most excited-electrons diffuse laterally interface, which time. positional make junction...
Abstract Reported is the first scalable synthesis of rac ‐jungermannenones B and C starting from commercially available inexpensive geraniol in 10 9 steps, respectively. The unique jungermannenone framework rapidly assembled by an unprecedented regioselective 1,6‐dienyne reductive cyclization reaction which proceeds through a vinyl radical cyclization/allylic isomerization mechanism. DFT calculations explain high regioselectivity observed cyclization.
Compared with normal PL, a red shift of upconversion PL spectrum is observed. Time-resolved and TA spectroscopies show FWHM peak position are changed at various times, which suggest the existence more than single excited state.
The lateral photovoltaic (LPV) effect has attracted much attention for a long time because of its application in position-sensitive detectors (PSD). Here, we report the ultrafast response LPV amorphous MoS2/Si (a-MoS2/Si) junctions prepared by pulsed laser deposition (PLD) technique. Different orientations built-in field and breakover voltages are observed a-MoS2 films deposited on p- n-type Si wafers, resulting induction positive negative a-MoS2/n-Si a-MoS2/p-Si upon illumination,...
The Raman spectra of all-trans-lycopene in n-hexane were measured under high pressure, and the results compared with those β-carotene. different pressure effects on are analyzed taking into account structures lycopene β-carotene molecules. It is concluded that: (a) vibronic coupling between S1 S0 states stronger than that lycopene, (b) diabatic frequency increment ν1 mode more susceptible to ν2 for (c) β-rings rotation can relieve effect C=C bond length This work provides some insights...
To date, plasmonic nanowire lasers mostly adopt hybrid waveguides, while there is a lack of study in terms the confinement effect and corresponding ultrafast dynamics non-hybridized lasers. Here, we report composed single CH3NH3PbBr3 on silver film without any insulating layer at room temperature. The exhibit lasing with around 1.9 ps decay rate 1 peak response time. Such values are among best ones ever reported. Interestingly, threshold same order as that their counterparts. low due to...
