Efficient extraction of charge carriers is critical for the creation of high-efficiency solar cells. Photoluminescence is proportional to the number of charge carriers in the perovskite and therefore sensitive to charge transfer into adjacent layers which makes photoluminescence based techniques invaluable for investigating the performance of new extraction layers. In this application note, the extraction efficiency of a VACNT hole extraction layer is investigated using PL spectroscopy with an Edinburgh Instruments FLS1000 Photoluminescence Spectrometer.

The terahertz spectral region, which falls between the microwave and infrared ranges, is one of the most promising regions of the electromagnetic spectrum for research and industry but it is currently underutilised in these areas. One of the most versatile sources for spectroscopy and imaging research in this region, is the Molecular Terahertz Laser. Find out how these lasers work and their applications in industrial and scientific imaging, materials analysis and biomedical research in this application note.

What is the best grating for your Raman spectrometer? Read this technical note to find out! The application team investigates a range of excitation wavelengths, and 5 different gratings to provide an insight into grating selection.

As photoluminescence (PL) research evolves, so does the demand for sensitive instrumentation to measure increasingly weak PL signals. Besides photon-counting detectors and monochromators with good stray light rejection, the source used to excite the sample is a key component to consider when designing an experiment.

Liquid scintillator detectors are widely utilised in neutrino and astroparticle detection experiments. One liquid scintillator that is increasingly being used in large scale detection experiments is linear alkylbenzene (LAB). LAB is an attractive scintillator due to its low cost, high flash point and low toxicity; making it easier to handle than previously used toxic and flammable organic solvents. LAB is commonly used together with the fluor 2,5-diphenyloxazole (PPO) which increases luminescence yield and shifts the luminescence to longer wavelengths.In this application note the properties of the liquid scintillator system LAB/PPO are investigated using time-resolved X-ray excited luminescence spectroscopy with the FLS1000 and XS1 X-ray Sample Chamber.

Forensic investigations often study extremely small samples which may need analysed by multiple techniques. Confocal Raman and Photoluminescence (PL) Microscopy are well-suited techniques for dealing with such samples. This application note details how Raman and PL microscopy can be used as an analysis tool in any forensic laboratory.
