Tunable excitation source for characterization of perovskite nanocrystals

Perovskite nanocrystals have photoluminescence quantum yields as high as 99% despite a very cheap and easy synthesis which make them an ideal candidate for future LEDs and other light-emitting applications.

A team of researchers in Professor A. S. Urban’s Nanospectroscopy Group at the Ludwig-Maximilians University in Munich is researching the optical and electronic properties of novel semiconductor materials such as perovskite nanocrystals.

To gain insight into the properties of perovskite nanocrystals, the team used an NKT Photonics supercontinuum laser, the SuperK EXTREME/FIANIUM with built-in pulse picker, in combination with the spectral filter, SuperK VARIA, as a tunable excitation source.
