TL;DR: In this paper, N-, O-, and S-tridoped carbon-encapsulated Co9S8 (Co 9S8@NOSC) nanomaterials are synthesized via simple pyrolysis of S- and Co(II)-containing polypyrrole solid precursors, and the materials are proven to serve as noble metal-free bifunctional electrocatalysts for water splitting in alkaline medium.

TL;DR: In this article, a review summarizes recent achievements concerning red phosphors mainly from three aspects: intensifying absorption bands and reducing lattice defects to increase quantum efficiency; selecting an appropriate coordination environment and altering the lattice symmetry to fine-tune the luminescence spectra; and reducing the nonradiative transition rate and preventing charge imbalance of a luminecence centre to enhance thermal stability.

TL;DR: In this article, a novel phosphate/tungstate family, K2Ln(PO4)(WO4) (Ln = Y, Gd and Lu) doped with Tb3+ and Eu3+ is synthesized via a conventional high-temperature solid-state reaction to explore new pure red phosphors with high critical concentration for white light-emitting diodes (WLEDs).

TL;DR: Detailed investigations of the crystal structure and the luminescence properties of Ba6Gd2(1- x)Ti4O17: xEu3+ reveal that the nonoccurrence of concentration quenching is related to the dimensional restriction of energy migration inside the crystal lattices.

TL;DR: It is the first time that white light is generated via accurate controls on the Ce3+-(Tb3+) n-Eu3+ energy transfer in such a widely studied host material and exhibits superior color stability and potential application prospect.
