Blue-light-excitable red-emitting phosphors with high thermal stability are essential for fabricating white light-emitting diodes (WLEDs). Herein, Ce3+-doped SrLaScO4 (SLO:Ce3+) phosphor is discovered to have an abnormal red emission band centered at 640 nm when excited 440 nm. Spectroscopy and structural analyses confirm that Ce3+ ions occupy the [LaO8] polyhedrons competitively, generating a ...

Flexible supercapacitors (SCs) have become a popular research topic due to their extra-long service life, foldability, and wearability. Nevertheless, low energy density restricts applications. Here, we synthesized phosphorus-doped bimetallic sulfides embedded in heteroatom-doped (N, S, P) carbon shells (P-ZCS/HC) using simple approach create high-performance flexible electrodes. The three-dimen...

The recently synthesized air-insensitive hydrogen doped KCr$_3$As$_3$ superconductor has aroused great research interests. This material has, for the first time in area of quasi-one-dimensional Cr-based superconductivity (SC), realized a tunability through charge doping, which will potentially significantly push development this area. Here based on band structure from first-principle calculatio...

we have performed density functional theory investigations on the adsorption properties of ammonia molecule on the undoped and n-doped tio2 anatase nanoparticles. we have geometrically optimized the constructed undoped and n-doped nanoparticles in order to fully understand the adsorption behaviors of ammonia molecule. for tio2 anatase nanoparticles, the binding site is preferentially located on...

First-principle calculations have been investigated to study the adsorption of the molecules (SO2, CO, NH3, CO2, NO2, and NO) on the surface of mono boron (B) B-doped and dual B-doped graphene sheets to explore their potential applications as sensors. Our findings indicate that the adsorption of (CO and NH3) on B-doped graphene and (CO and ...

More than fifteen years after the high temperature superconductivity discovery, antiferromagnetic (AF) fluctuations pairing mechanism[1] is still highly controversial. However, inelastic neutron scattering (INS) measurements have successfully brought to light the existence of unusual AF excitations that develop below Tc and could be the hallmark of an unexpected spin-1 collective mode, tightly ...
