The crystallite size and crystallinity of the film increase at annealing temperature of 400 °C, and there is no obvious change at annealing temperatures of 200 °C and 300 °C.

We establish that doping with 4 · 1018 cm−3 iron concentration leads to a decrease of the band gap by 8 ± 1 meV compared to non-doped CdTe. We show that, in the spectral range of 1.2–1.6 eV, the luminescence of crystals is mainly defined by Hydrogen-like donors and two types of acceptors with binding energies of 149 ± 5 meV and 45 ± 2 meV. In addition, we detect the luminescence bands with maxima of 1.1 eV and 0.95 eV in the longer wavelength region. The characteristic decay time for each of the bands is 0.386 ms at 7 K. The observed bands are ascribed to intracenter luminescence corresponding to the 3T1(3H) → 5E(5D) and 5T2(5D) → 5E(5D) transitions between Fe2+-ion inner shells.

We also find that the splitting light spots heal into a Gaussian-like spot due to the turbulence effect, smaller ellipticity, larger topological charge, slower healing process. It can be also found that PCEV beam propagates along a downlink path is less affected by atmospheric turbulence in comparison with uplink path. In order to confirm our numerical results, we combine the complex screen method and multi-phase screen method to simulate the propagation of the PCEV beam in atmospheric turbulence.

The outcomes also reveal that the effect of oceanic turbulence on the propagation properties of PCTLGV beam can be effectively mitigated by regulating the twist factor and topological charge. We also find that PCTLGV beam exhibits stronger anti-turbulence ability, when the topological charge and twist factor have opposite signs as well as larger absolute values of twist factor. In addition, the PCTLGV beam will degenerate fast in stronger turbulence over the poor turbulence, which can be counteracted by increasing the initial coherence lengths.
