FLS1000 Photoluminescence Spectrometer
In addition to their remarkable photovoltaic performance, halide perovskites have also been found to have excellent light emitting properties and perovskite LEDs are subsequently being extensively researched as a new class of solid-state light emitters. One particularly promising application is the creation of a solid-state white-light emitter. In current commercially available solid-state white-light sources, a combination of multiple light emitting diodes and phosphor coatings must be used to generate the white emission. However, this multicomponent approach is problematic as the components age at different rates and the colour will therefore drift over time.
In this application note, the properties of a white-light emitting 2D perovskite led material are characterised with steady state and time-resolved photoluminescence spectroscopy using the FLS1000 Photoluminescence Spectrometer and the chromaticity coordinates and lifetime of the emission determined.
