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.
