CdSe polycrystalline films were deposited by a close-spaced vacuum sublimation method at different substrate temperatures (Ts) using glass slides as substrates. At Ts ≤ 673 K the films have a structure with strong dispersion of grain size (d) (from 0.1 to 0.3 μm). In this case the layer-by-layer mechanism determines the growth process of the layers. For Ts=873 K they have a columnar-like structure with a clear growth texture and the average grain size d=3-4 μm. The films obtained at Ts > 473 K are n-type and only correspond to a single wurtzite phase. The crystallites are preferentially oriented with the (102) planes parallel to the substrate. At lower temperatures the films are bi-phase. The microstress level in CdSe films obtained at Ts=873 K (0.5 × 10-3) is considerably smaller than for the films deposited at Ts=773 K (4.0 × 10-3). Increase of the value of Ts improves the stoichiometry of CdSe films. Analysis of the low-temperature photoluminescence (PL) spectra let us determine the nature and energy of point and extended defects in the investigated films. It was shown that the films contain Na(Li) and P residual impurities. The results of the structural and PL measurements showed that the CdSe polycrystalline films are of fairly good crystal and optical quality for Ts=873 K and can be suitable for various applications.
