The nanosecond luminescence spectroscopy setup is used for luminescence measurements in UV-VIS spectral regions. Luminescence measurements under stationary and quasi-stationary conditions, and with nanosecond time resolution in a spectral range of 180-850 nm can be performed using this setup.

Double monochromator with photomultiplier tube is used for high spectral resolution measurements.
ICCD is used for time-resolved luminescence measurements.
CW He-Cd laser (325 nm), nanosecond YAG:Nd laser and its harmonics (up to 5th, 213 nm), and tunable wavelength laser (210-2300 nm) can be used for excitation.
Measurements can be performed in a wide temperature range 8-300 K, using closed cycle cryostat.
Spectral range of photomultiplier tube: 160-930 nm.
Spectral range of ICCD: 180-850 nm.
