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.

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.

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.

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.
