recommendations! Published in 2019 at "Scientific Reports"

DOI: 10.1038/s41598-019-38815-0

Abstract: Optically stimulated luminescence (OSL) dating of sediment, based on the accumulation of trapped charge in natural crystals since their last exposure to daylight, has revolutionised our understanding of the late Quaternary period. Recently, a complementary… read more here.

DOI: 10.1038/s41598-022-05113-1

Abstract: Portland cement emits bright near-infrared photoluminescence that can be excited by light wavelengths ranging from at least 500–1000 nm. The emission has a peak wavelength near 1140 nm and a width of approximately 30 nm.… read more here.

DOI: 10.1039/d2dt00983h

Abstract: Erbium metallofullerenes exhibit near-infrared photoluminescence from the Er3+ ions, which has potential applications in telecommunications, optical devices and bioscience. In this manuscript, we report the construction of a supramolecular complex of metallofullerene Er3N@C80 and cycloparaphenylene… read more here.

DOI: 10.1088/1361-6528/ab8f4e

Abstract: Embedded gold (Au) nanoparticles (NPs) are formed in Mg:Er:LiNbO3 single crystals by Au ion implantation and subsequent thermal annealing. Absorption of the Mg:Er:LiNbO3crystals with Au NPs is found to be enhanced significantly in visible light… read more here.

Sign Up to like & get
recommendations! Published in 2020 at "Frontiers in Chemistry"

DOI: 10.3389/fchem.2020.00327

Abstract: Electrocatalytic reactions such as oxygen evolution (OER) and oxygen reduction reactions (ORR) are one of the most complex heterogeneous charge transfer processes because of the involvement of multiple proton-coupled-electron transfer steps over a narrow potential… read more here.
