Application Note: Comparing Hole Extraction Efficiencies in Perovskite Solar Cells using Photoluminescence Quantum Yield

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.


Application Note: Terahertz Molecular Lasers - Introduction & Applications

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.


Application Note: 3D Raman Mapping of a Transdermal Patch

How can Raman microscopy help the battle to quit smoking? Read this latest application note to find out how the RMS1000 can aid pharmaceutical laboratories quality control nicotine patches via 3D Raman mapping.


Application Note: Energy Transfer in a Liquid Scintillator Investigated using Time-Resolved X-ray Excited Luminescence Spectroscopy

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.


Application Note: Confocal Raman and Photoluminescence Microscopy for Forensic Investigations

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.


Application Note: Imaging Charge Extraction in VACNT Perovskite Solar Cells using Spectral and Lifetime Confocal Photoluminescence Mapping

In this application note, the hole transfer into a VACNT based hole extraction layer is imaged using steady-state and time-resolved confocal PL microscopy with an Edinburgh Instruments RMS1000 Confocal Raman & PL Microscope.


Application Note: Time-resolved Spectroscopy of Phosphorescent Oxygen Sensors in a Relevant in vitro Environment for Biomedical Applications

This customer written application note details how researchers from the Air Force Research Laboratory have outfitted an Edinburgh Instruments FLS1000 Photoluminescence Spectrometer to assess candidate dissolved oxygen sensors.


Application Note: Gemstone Identification Using Raman Microscopy

The gemstone industry suffers massively from forgeries that even highly experienced jewellers cannot determine. Read this application note to discover how Raman microscopy offers itself as a useful technique in the identification of gemstones.


Application Note: Raman Microscopy of Graphene

Graphene is the thinnest material known to exist, whilst also being extremely strong - around 200 times stronger than steel. Graphene is an excellent conductor of electricity and heat as it is optically transparent. The applications of graphene are extensive, and include energy storage, photodetectors, and computer chips. In this application note we highlight how Raman microscopy is an essential tool for any material scientist researching graphene.


Application Note: Raman Spectroscopy as a Tool for Studying Polymer Phase Transitions

Semicrystalline polymers are the largest group of commercially produced plastics. Heating and cooling of these polymers between phase transitions is used industrially to shape polymers into their final product. In this application note the RMS1000, with a heated stage, is used to observe phase transitions in two polymers; polyethylene, and nylon-6.
