Hollow Zn-doped Fe2O3 nanospheres were fabricated by a facile solvothermal method followed post-annealing treatment. The as-synthesized hollow have uniform size with diameter of about 200–500 nm. growth mechanism the was proposed based on many contrast experiments. Compared without Zn doping, showed an improved electrochemical performance in terms high rate capability and long cycling performance. At current densities 1 A g−1 2 g−1, exhibited initial capacity 861.5 698.4 mA h respectively,...
9,10-Diphenylanthracene cubic nanoparticles (DPA CNPs) with aggregation-induced emission characteristic (AIEgens) were synthesized through a facile reprecipitation method; then, bright and stable electrochemiluminescence (ECL) signal can be observed when the DPA CNPs modified at glassy carbon electrode (GCE) in presence of Tri-n-propylamine (TPA). This phenomenon is ascribed to molecules restricted movement that greatly blocked energy leakage during relaxation excited state, which...

Developing light-harvesting materials with broadband spectral response has constantly been at the forefront of photonics and science. The variation in dopants hosts allows for extension response, but construction down-conversion phosphor covering entire ultra-violet region remains a daunting challenge. Here, we describe material system which amorphization N-doping notably extend response. We demonstrate that fabricated nitrided amorphous TiO2 activated high concentration Eu3+ (∼15 mol %) can...

We demonstrate Li+-doping engineering for improving the near-infrared (NIR) photoresponse in an Er3+-activated Y2O3 phosphor. show that rational incorporation of Li+ results a large enhancement upconversion (UC) emission intensity up to 29 times upon excitation NIR light. The improved UC properties could be associated with enhanced dipole–dipole transition probability due Li+-induced changes local site symmetry Er3+ ions and improvement crystallinity samples. further construction...
Abstract Spinel glass–ceramic is an important class of composites with promising applications in transparent antiriot shields, tunable lasers and broadband optical amplifiers. Although the crystallization process spinel has been well studied, approach for tuning it response resultant still need urgent attention.
