Elucidating Photocatalysis Mechanisms using Transient Absorption; Energy and Electron Transfer in Ni-Amine Complexes for C-N Cross-Coupling Reactions

Light-driven photocatalytic reactions are featured prominently across all fields of science, from the energetically uphill processes of photosynthesis in plants, to water-splitting solar fuels, and even disinfection of water, and improving synthetic reactions.

Kinetics of Photocatalysis Reactions Studied by Transient Absorption Spectroscopy

Photocatalysis is the rate increase of a chemical reaction by light, often in the presence of a catalyst that starts the reaction upon irradiation. Photocatalysts are typically semiconducting metal oxides such as ZnO, Fe2O3 or TiO2 which are employed as particles in solution. When absorbing light, these materials are able to generate electrons and holes which go on to react with chemical species on their surface. Find out how our LP980 Spectrometer was used in this recent application note.

Fluorescence, Delayed Fluorescence and Phosphorescence Spectra of a TADF Emitter Measured using the FLS1000 with a VPL laser and Gated PMT Detector

Materials exhibiting thermally activated delayed fluorescence (TADF) have attracted widespread research attention as a new generation of high-efficiency emitters for use in Organic Light Emitting Diodes (OLEDs). In a TADF OLED, triplet excitons are converted to singlet excitons through a thermally assisted reverse intersystem crossing which enables internal quantum efficiencies of 100% to be achieved.1
