“…For the purpose of engineering defective TMPs to boost HER, some research progress has been made. Zhou and co‐workers reported an all‐in‐one surface engineering method to fabricate defective Ni 2 P arrays grown on carbon foil (Ni 2 P/CF‐ x ; x represents the amount of sodium hypophosphite: 10, 30, 50, 500) . During the phosphorization process, neither excessively phosphorized Ni 2 P/CF‐500 nor inadequately phosphorized Ni 2 P/CF‐10 gave rise to the formation of enriched defect sites, whereas Ni 2 P/CF‐30 prepared by subtly controlling the amount of sodium hypophosphite had a high number of Ni vacancy defects.…”

As hydrogen has been increasingly considered as promising sustainable energy supply, electrochemical overall water splitting driven by highly efficient non‐noble metal electrocatalysts has aroused extensive attention. Transition metal phosphides (TMPs) have demonstrated remarkable electrocatalytic performance, including high activity and robust durability towards hydrogen evolution reaction (HER) in acidic and alkaline as well as neutral electrolytes. In this Review, up‐to‐date progress of TMP‐based HER electrocatalysts is summarized. Various synthesis strategies of TMPs based on selected phosphorus sources are presented, and the reaction mechanisms of HER as well as the contribution of phosphorus in the TMPs to HER activity are briefly discussed. The multiscale approaches for promoting the activity and stability of TMP‐based catalysts are discussed with respect to intrinsic electronic structure, hybrids, microstructure, and working electrode interface. Some crucial issues and future perspectives of TMPs are pointed out. These modulated approaches and challenges are also instructive for constructing other high‐activity energy‐related electrocatalysts.

“…However, it is still a challenge to achieve multi-color output and enhanced red UCL in a single fixed composition of Yb/Er co-doped system. Recently, some dopants, such as divalent manganese (Mn 2+ ), have been recognized as effective elements which can decrease the short-wavelength green emission and enhance the long-wavelength red emission because of the energy transfer between Er 3+ and Mn 2+ ions (Tian et al, 2012; Liu et al, 2019).…”

In thiswork, we investigate the influence of Mn 2+ on the emission color, thermal sensing and optical heater behavior of NaGdF 4 : Yb/Er nanophosphors, which the nanoparticles were synthesized by a hydrothermal method using oleic acid as both a stabilizing and a chelating agent. The morphology and crystal size of upconversion nano particles (UCNPs) can be effectively controlled through the addition of Mn 2+ dopant contents in NaGdF 4 : Yb/Er system. Moreover, an enhancement in overall UCL spectra of Mn 2+ doped UCNPs for NaGdF 4 host compared to the UCNPs is observed, which results from a closed back-energy transfer between Er 3+ and Mn 2+ ions ( 4 S 3/2 (Er 3+ ) → 4 T 1 (Mn 2+ ) → 4 F 9/2 (Er 3+ )). The temperature sensitivity of NaGdF 4 :Yb 3+ /Er 3+ doping with Mn 2+ based on thermally coupled levels ( 2 H 11/2 and 4 S 3/2 ) of Er 3+ is similar to that particles without Mn 2+ in the 303–548 K range. And the maximum sensitivity is 0.0043 K −1 at 523 K for NaGdF 4 :Yb 3+ /Er 3+ /Mn 2+ . Interestingly, the NaGdF 4 :Yb 3+ /Er 3+ /Mn 2+ shows preferable optical heating behavior, which is reaching a large value of 50 K. These results indicate that inducing of Mn 2+ ions in NaGdF 4 :Yb 3+ /Er 3+ nanophosphors has potential in colorful display, temperature sensor.
