The refractive index and the E0 energy gap has been determined for a number of Zn1−xMgxSySe1−y alloys with x≤0.3 and y≤0.3 at temperatures between 5 and 300 K. It has been shown that the refractive index can be empirically expressed as a function of the E0 energy gap. Furthermore we have determined the temperature dependence of the E0 energy gap and hence the temperature dependence of the refractive index for these alloys.
