Bulk Cr2O3 is an antiferromagnetic oxide that exhibits the magneto-electric effect at room temperature, with neither spontaneous magnetization nor net electric polarization. These physical properties stem from a subtle competition...
Boosting substrate-molecule interactions, especially the strong vibronic coupling and efficient photo-induced charge transfer (PICT) transitions, are critical issues to improve surface-enhanced Raman scattering (SERS) sensitivity of non-metal substrates. Here, by...
Color-tunable long persistent luminescence (LPL) phosphors are more strongly desired for intelligent anti-counterfeiting and information storage compared with single color types.
Two composite layers are used to enhance the efficiency of Si-based near-infrared perovskite light-emitting devices, which are produced in ambient air, and the external quantum efficiency increased to 7.5%.
Chiral gold(I) isocyanide complexes [Au(p-C6F4OR1)(p-CNC6H4(O2CC6H4(OR2)] with R1, R2 or both being (R)-2-octyl, display an interesting and unprecedented response to mechanical or thermal stress. For all the complexes, heating leads to...
Cs-based perovskite nanocrystals (PeNCs) have been considered to be superb emitters for perovskite light-emitting diodes (PeLEDs) due to their remarkable optoelectronic properties. Still, poor optical properties are mainly attributed to...
Fundamentals of doping engineering strategies of metal oxide semiconductors and various charge transfer processes for emerging SERS applications are discussed.
Noncentrosymmetric (NCS) structure is the precondition for second-order nonlinear optical (NLO) materials. In this work, we present a new strategy for constructing NCS structures, that mixed alkali-metals made a new...
Efficient triplet-to-singlet conversion in conventional donor-acceptor TADF compounds relies on charge-transfer (CT) and locally-excited (LE) triplet state mixing as this provides required spin-orbit coupling. In this work, asymmetric carbazole-donor motif...
