Photoluminescent properties of GaInP2 films grown by metal-organic vapor phase epitaxy (MOVPE) on two different substrates (GaAs and Ge) are studied. The grown GaInP2 films were nearly lattice matched to GaAs, had the same thickness of approximately 0.5 m and different values of ordering parameter. Photoluminescence (PL) measurements were performed in a wide temperature range (10 - 300 K) for polarization of the emitted radiation along the  and [ 0 1] directions. The temperature dependence of the photoluminescence intensity ratio for two polarizations was calculated and found experimentally. To estimate the value of the energy separation between the heavy-hole and light-hole bands a simulation of the spectra was realized using parabolic bands and Boltzmann statistics.
