Engineering new materials with unique and valuable electronic and optical properties is paramount in the design of new devices from memory storage to creating the next generation of organic photovoltaic solar cells.

Semiconductor quantum dots (QDs) have unique tuneable photoluminescence properties which lend them to a range of important technological applications including solid-state lighting, displays, photovoltaics, and biomedical imaging. Indium phosphide (InP) QDs have attracted significant interest as an environmentally friendly and non-toxic alternative to traditional heavy metal based QDs containing cadmium and lead.

The ability of plants to live, thrive and survive on sunlight provides unsurpassed motivation to understand and mimic this process for solar energy production. In this application note, Edinburgh Instrument's LP980 Transient Absorption Spectrometer is used to measure energy and electron transfer events.

In this technical note we describe the operation of Batch Mode and demonstrate two examples where it is useful: temperature maps of anisotropy and measurements on multiple samples.

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.

This technical note will introduce some basic theory about polarisation of light and polarised Raman spectroscopy, before demonstrating different types of samples the RM5 can analyse using this technique.

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.

This scientific publication discusses the first time formation of resonantly coherent J-aggregates on carbon nanotubes with highly efficient energy transfer from the aggregates to the nanotubes.

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
