  Identifying Thermally Activated Delayed Fluorescence (TADF) using an FS5 Spectrofluorometer

Identifying-Thermally-Activated-Delayed-Fluorescence-FS5-SpectrofluorometerThermally activated delayed fluorescence (TADF), also known as E-type delayed fluorescence, was first observed in 1924 by Francis Perrin.1,2 In 2012 it received a resurgence in attention, and exposure to a wider audience, when Professor Chihaya Adachi and colleagues at Kyushu University used the TADF mechanism to harvest triplet excitons in organic light emitting diodes (OLED) and create a new type....

 

  Electroluminescence and Photoluminescence Spectroscopy of a Phosphorescent Organic Light Emitting Diode

edinburgh instrumentsOur daily experience with organic (carbon based) materials such as polyethylene shopping bags and polyvinyl chloride insulation on cables suggests that they should be electrical insulators and this is indeed true for the majority of organic materials. However, there exists a small subset of organic materials with a particular electronic structure that are semiconducting in nature and can be used to make optoelectronic devices such as light emitting diodes...

 

  Photophysical Characterisation of Perovskite Quantum Dots

Semiconductor quantum dots possess an array of attractive properties, including; high photoluminescence quantum yields (PLQY), solution processability and highly tuneable band gaps. These properties make quantum dots ideal for optoelectronic devices such as light emitting diodes and semiconductor lasers where they serve as emitters or in photodiodes and solar cells where they serve equally well as light absorbers. In addition, their light emission properties also make them a promising new class of fluorescent probe for biomedical fluorescence imaging...

 

  Temperature-Dependent Absolute Photoluminescence Quantum Yield (PLQY) Measurements of a Halide Perovskite

Variation of the Photoluminescence Quantum Yield of CsPbBr3 Perovskite with TemperatureHalide perovskites are a promising class of materials for a wide variety of optoelectronic applications such as photovoltaics, light emitting diodes, lasers and optical sensing. They have received widespread attention due to their many attractive synthetic and photophysical properties, namely: solution processability, high tunability, long charge carrier lifetimes and high charge carrier mobilities...

 

  Studying the Carrier Lifetime in Perovskite Photovoltaic Cells Using the FLS1000

FLS 1000We are happy to share our latest application note where we demonstrate how the FLS1000 Photoluminescence Spectrometer can be used for studying the carrier lifetime in perovskite photovoltaic cells. We are pleased to have worked alongside the research group of Prof. Ifor Samuel at St Andrews University. Halide perovskite materials are revolutionising the field of solar cell research thanks to their low cost and high efficiency...

 

  Edinburgh Instruments New Middle-East Platform

Edinburgh Instruments parent company, Techcomp (Europe) Ltd (TEU), has acquired Dubai based AASolutions FZCo and re-named the business Techcomp (Middle East) FZCo (TME). This new Middle-East office enables Edinburgh Instruments to have a local platform in the region for supporting future sales and service requirements. In addition, TME will offer sales and service support for other leading Techcomp brands such as Scion Instruments...

 

  FS5 Sample Cassettes Undergo Facelift

Edinburgh Instruments is excited to share the latest upgrades to our FS5 Sample Cassettes range. The easy-to-use cassettes see improvements that provide users ease of access, and time-saving features that makes operation more straightforward. With the use of a new, harder wearing material, the cassettes include a ‘Plug n Play’ feature that allows our Fluoracle Software to automatically recognise which measurement module is being used....
