Photoluminescence experimental set-up


The instrument specially designed for measuring PL spectra, PLE and Photoluminescence quantum efficiency (PLQE) for Organic and polymer luminescent materials of both solution and thin film phase.

Unique features:

The PL set up consists of following component.

  • Xenon arc lamp 450 W, coupled to TRIX 190 monochromato

  • The integrating sphere itself with a sample holder and two ports (entrance/exit) from sphere optics.

  • The detection system, including a monochromator (Triax 320)including three grating and photomultiplier Tube (PMT).
