Sažetak
A series of Cu_6P(S_1-xSe_x)_5Br solid solutions was studied at room temperature by X-ray diffraction and optical absorption measurements in the whole compositional range (0<=x<=1). The optical pseudogap, the absorption edge energy width, the cubic lattice parameter and calculated density of these mixed crystals were all found to change non-linearly with the composition x. These non-linear compositional dependencies were attributed to the effect of compositional disordering on the energy position and shape of exponential fundamental optical absorption edge in Cu_6P(S_1-xSe_x)_5Br.
