Application Note: Raman Mapping of Layer Number, Strain, and Structural Defects in Graphene

In this Application Note, the capability of the RM5 and Ramacle® software for graphene analysis is demonstrated by mapping the layer number, strain, and defects on graphene films.


Application Note: Angle-Resolved Polarised Raman Microscopy for Determining the Orientation of Carbon Nanotubes

This Application Note demonstrates how the alignment of carbon nanotube architectures can be probed using angle-polarised Raman microscopy with the Edinburgh Instruments RM5


Application Note: UV-Vis Spectroscopy for Characterising the Optical Properties of Gold Nanoparticles

UV-Vis spectroscopy is routinely used in analytical science in part because it is a simple way of studying a sample’s optical properties over the UV and visible regions of the electromagnetic spectrum. Here, we used the DS5 UV-Vis Spectrophotometer to study the unique and interesting effects that occur when gold nanoparticles interact with light. Read to find out more.


Application Note: High-Resolution Raman & Photoluminescence Imaging of MoS2

In this application note, the transition-metal dichalcogenide molybdenum disuflide (MoS2) is characterised using the RM5 Confocal Microscope with Raman and photoluminescence imaging to characterise its layer-dependent optoelectronic properties.


Application Note: Multimodal Raman, Photoluminescence & SHG Imaging of CVD Grown WSe2

In this application note, the transition-metal dichalcogenide tungsten diselenide (WSe2) is characterised using the RMS1000 Confocal Microscope with five imaging modalities: reflected brightfield & darkfield, Raman, photoluminescence and second harmonic generation to fully characterise its layer-dependent optoelectronic properties. The multimodal capabilities of the RMS1000 Confocal Microscope make it an ideal imaging platform for studying the optoelectronic properties of transition-metal dichalcogenides.


Application Note: Rapid Excitation Emission Matrix Analysis of Single Wall Carbon Nanotubes

Single-wall carbon nanotubes (SWCNTs) have unique electrical, thermal, mechanical, and optical properties which make them attractive for a wide variety of applications; ranging from drug delivery to battery electrodes. In this application note the FLS1000 Photoluminescence Spectrometer equipped with an InGaAs NIR camera is used to identify the chiral indexes present in a SWCNT sample using excitation emission matrix spectroscopy.


Application Note: Tuning the Photoluminescence of Graphene Oxide

Graphene has received tremendous attention within both the scientific community and industry due to its remarkable electrical, thermal and mechanical properties. In this application note, the photoluminescence properties of graphene oxide are investigated using an FLS1000 Photoluminescence Spectrometer equipped with double excitation and emission monochromators and an infrared PMT.


Application Note: Photophysical Characterisation of Perovskite Quantum Dots

Perovskite Quantum Dots are a promising new class of light emitters. In this application note a complete photophysical characterisation, comprising of absorption spectra, photoluminescence spectra, photoluminescence lifetime, and quantum yield of two perovskite quantum dots is carried out using the versatile FS5 Spectrofluorometer.


Photogenerated Excited States in Solubillized Single-Wall Carbon Nanotubes; Transient Absorption and Oxygen Dependence of the Triplet

Single-walled carbon nanotubes (SWCNT) feature immense tensile and thermal strength with advantageous 1-dimensional molecular wire electronic properties. The Edinburgh Instruments LP980 Transient Absorption Spectrometer is well suited to study these photo-generated excited states, especially with the capability to add near-infrared (NIR) detectors needed to capture the transient species in these materials.


Luminescence Thermometry with Upconversion Materials

Many upconversion luminescent materials emissive properties change as a function of temperature, pressure, or the presence of a chemical species. Such properties have long been exploited in the development of luminescence-based sensors. In this application note, we discuss how the use of luminescence thermometry changes the emissive properties of upconversion materials.
