A convenient one-step solvothermal process to construct TiO2 nanoparticles anchored onto NH2-MIL-88B(Fe) with enhanced adsorption capacity and photocatalysis performance was reported. The TiO2@NH2-MIL-88B(Fe) (abbreviated SU-x) exhibited excellent photodegradation toward methylene blue (MB) from simulated wastewater under the irradiation of visible LED light. catalytic capability can be mostly attributed improved efficiently photogenerated electrons transported conduction band that...
Pyrene is considered as one of the most promising nonlinear functional building blocks.
Abstract Two multi‐walled carbon nanotube (MWCNT)‐based nanohybrids, MWCNT–ZnTPP and MWCNT–TPP (TPP=5‐[4‐{2‐(4‐formylphenoxy)‐ ethyloxy}phenyl]‐10,15,20‐triphenylporphyrin, ZnTPP=5‐[4‐{(4‐formylphenyl)ethynyl}phenyl]‐10,15,20‐triphenylporphinatozinc(II)), were prepared directly from pristine MWCNTs through 1,3‐dipolar cycloaddition reactions. Covalent attachment of the porphyrins to surfaces was confirmed by Fourier transform infrared spectroscopy, ultraviolet/visible absorption,...
Yb 3+ / Er codoped La 2 S 3 upconversion ( UC ) phosphors have been synthesized using high‐temperature solid‐state method. Under 971‐nm excitation, the maximum luminescence power can reach 0.64 mW at excitation density of 16 W/cm and an absolute yield 0.36% was determined by method , quantum : (green ~0.18%, red ~0.03%, integration ~0.21) comparable to that NaYF 4 nanocrystals (integration ~0.005–0.30). Frequency upconverted emissions from two thermally coupled excited states were recorded...

MWCNTs/TiO2 nanocomposites have been prepared by a hydrothermal method and characterized various spectroscopic techniques, an enhanced optical nonlinearity was observed for M1.00 due to combination of mechanisms.
Intramolecular charge transfer (ICT) is an important factor in the nonlinear optical (NLO) properties of organic molecules. In order to study effect ICT on two-photon absorption (TPA) and excited-state (ESA), three chalcone derivatives (1, 2 3) with different electron push-pull systems were designed synthesized. The performance these depends mainly includes ultrafast femtosecond time domain long-lived state (CTS) picosecond domain, which dominate molecular TPA ESA respectively. Hole-electron...
Abstract In this study, using only a single pulse, pump-probe measurement with large time window of more than 100 ps is implemented. A commercial grating used to encode ∼56 in pulse; therefore, there no need for machining customization. addition, technique, the surface accurately imaged, eliminating image blur problem caused by phase differences previous echelon-based techniques. Moreover, make full use and obtain larger window, simple reflection echelon combined that matches window. This...
Abstract In this research, we studied the ultrafast dynamics and phase transition of VO2 films with different thicknesses. Using transient absorption spectroscopy, two thicknesses 59.5 148 nm showed broadband excited state from 450–750 nm, maximum peak was at ~450 nm. Under low excitation fluences, exhibit three sequential dynamic processes time scales femtoseconds (fs) to nanoseconds (ns). Depending on film thickness fluence, a is observed in scale ~21 ps when fluence reaches 1.27 mJ/cm2....
Fully understanding and modulating the nonlinear absorption in GaN are crucial for designing ultrafast photonic devices. In this work, both ultra-broadband transient spectra carrier recombination time were found to be significantly altered by carbon defects. An energy band model defect dynamics was established based on photoluminescence spectroscopy. Our discernibly reveals that CN tri-carbon intricately modulate spectrum capture process: The rapid of holes reduces hole hundreds femtoseconds...

Two simple hydrazone derivatives (A1 and A2) linked with different Π-conjugated systems are designed synthesized to reach ultrafast broad-band optical limiting (OL) under pulse widths. To exploit various virtues of two-photon absorption (TPA)-induced excited-state (TPA–ESA), ESA is successfully established on a singlet state. Both compounds show range from 556 750 nm relatively long lifetime. A1 displays larger reverse saturable than A2 in the multiwavelength Z-scan experiments. Furthermore,...
Thermal-sensitive materials, such as metallosupramolecular polymers, have been integrated into devices for a broad range of applications. However, the role these materials is limited to temperature sensing and lack memory function. Herein, we present novel [PolyCo-L1xL2y-PF6]-based organic resistive memories (ORMs) possessing both thermal response ternary behavior with three electrical resistance states [high (HRS), intermediate (IRS), low (LRS)]. Furthermore, can be memorized by...
