Programming language: C.
Computer: Any computer running a GCC compiler.
Operating system: Linux, Mac OS X, Windows (+Cygwin).
RAM: Several ten - several hundred MB depending on number of recorded PL spectra.
Keywords: Luminescence mappings, Thin film semiconductor, Lateral fluctuation, Opto-electronic properties, Splitting of quasi-Fermi levels, Evaluation software.
Classification: 7.4.

External routines: GNU Scientific Library, libpng, GNU OpenMP

Nature of problem:
Evaluation of PL spectra and extraction of opto-electronic properties including integrated PL yield, splitting of quasi-Fermi levels and optical band gap. The spectral shift of the PL spectra is covered by use of an adaptive fit procedure.

Solution method:
Adaptive linear fit of the high energy slope.

Restrictions:
For a full analysis, the PL spectra must satisfy the requirements of Planck's generalized law regarding the steady-state condition, the absorption of high-energy photons and that the relaxation time is fast then the recombination time. The experimental setup must be spectrally calibrated.

Unusual features:
Adaptive linear fit, implemented parallelization.

Running time:
A few seconds - a few minutes
