Article Abstract
A series of Sr(PO):Ce/Mn/Tb phosphors were synthesized by a high temperature solid phase method. After introducing Ce as sensitizer in Sr(PO):Ce/Mn, the efficient energy transfer from Ce to Mn was observed and analyzed in detail, and Sr(PO):Ce/Mn was demonstrated to be color tunable, changing from blue to orange red. In addition, Tb ion, which mainly emits green light, was further added into the Sr(PO):Ce/Mn. Due to the addition of this green emission, the white emitting phosphors with good quality were obtained. At the same time, the energy transfer mechanisms among Ce, Tb and Mn ions were also analyzed in detail. The results show that Sr(PO):Ce/Mn/Tb is a promising candidate for white light emitting diodes.

Background: Of the mycotoxins, aflatoxin is the most significant. The detection of aflatoxin B1 (AFB1) is crucial for ensuring food safety, as this highly carcinogenic toxin readily contaminates crops such as grains and nuts, and timely detection can effectively prevent associated health risks. The selection of luminophores is of paramount importance in the detection of ECL (electrochemiluminescence).

Against the backdrop of global carbon neutrality target driving the transformation of energy structure, alcohol fuel cells (AFCs) show great application potential; However, the sluggish kinetics of their anodic alcohol oxidation reaction hinders the commercialization of AFCs. Metallene is a novel 2D material with potential application prospect in the field of electrocatalysis. In this paper, PdMoW trimetallene has been successfully produced by a one-pot wet-chemical method, which displays a unique two-dimensional curved ultrathin graphene structure.
