Researchers in Fujian, China, led by Rong Cao and Zu-Jin Lin, have developed a new method for sensing ClO- employing fluorescence spectroscopy and novel metal organic frameworks. The authors used an Edinburgh Instruments FS5 Spectrofluorometer to characterize and optimise the sensor’s response towards ClO- . They then employed this sensor to detect ascorbic acid, an essential nutrient for the human body.

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.

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
