ARETUSA—advanced research equipment for fast ultraweak luminescence analysis: new developments

ARETUSA is a new set-up, developed in at LNS-INFN which allows to perform accurate and reliable photoluminescence measurements, in single photon counting mode, with 337–700 nm excitation wavelength and 400–800 nm emission wavelength. It performs time resolved analysis starting from few microseconds after the illumination. New improvements of this set up are described and some new exciting results are reported.
