《Synthesis and Spectroscopy of Emissive, Surface-Modified, Copper-Doped Indium Phosphide Nanocrystals》 was published in ACS Materials Letters in 2020. These research results belong to Mundy, M. Elizabeth; Eagle, Forrest W.; Hughes, Kira E.; Gamelin, Daniel R.; Cossairt, Brandi M.. Computed Properties of Br3In The article mentions the following:
Aminophosphine precursors were used to synthesize Cu-doped InP nanocrystals (NCs) via direct doping in a slow-injection bottom-up method and postsynthetic cation exchange. By both methods, the amount of Cu incorporated into the NCs could be tuned simply by varying the molar ratio during synthesis. Common postsynthetic surface modifications such as Lewis acid treatment and Zn chalcogenide shelling were performed on these samples, resulting in an enhancement of the Cu-based emission from 10% to 40%. For samples with thick shells, the Cu-based luminescence quantum yield reached over 60%, a record value for doped InP NCs. Time-resolved luminescence spectroscopy showed increasing carrier lifetimes after surface treatments concurrent with the disappearance of a 2 ns decay process previously attributed to surface trapping in native InP NCs, showing the broad applicability and consistent impacts of the surface treatments. In this way, a route to obtain high-quality near-IR emitters using less toxic alternatives to the popular Pb- and Cd-containing materials was developed. In the experiment, the researchers used Indium(III) bromide(cas: 13465-09-3Computed Properties of Br3In)
Indium(III) bromide(cas: 13465-09-3) is used in organic synthesis as a water tolerant Lewis acid. It efficiently catalyzes the three-component coupling of β-keto esters, aldehydes and urea (or thiourea) to afford the corresponding dihydropyrimidinones.Computed Properties of Br3In
