Monocrystals of sphalerite‐type CdTe 1‐x Se x were grown by self‐selecting vapour growth SSVG in the horizontal configuration. As measured on a series of points of a (110) split plane, the “rocking curve” half‐width was below 30 arcsec, while the lattice parameter measurements demonstrated the molar fraction x varying within 0.0024 (0.24 %). The values of x obtained from photoluminescence spectra taken from samples of different quality were in the ranges of 0.0034 (0.34 %) and 0.0047 (0.47 %). On the basis of the photoluminescence measurements, the maximum difference in x within the crystallised material was estimated to be 0.01 (1 %).
