From 2022, an experimental device for measuring time-resolved cathodoluminescence is available in our labs. It is a unique tool for measuring luminescence excited by accelerated electrons. We can therefore measure both spectra and decays. The pulse width can be down to 8 ns, so we can measure relatively fast decays. A temperature stage is also available, so we will be able to measure even at lower temperatures down to 50 K.
