We present the growth and optical properties of Pb1−xEuxTe films (0<x<0.55) prepared by a co‐evaporation technique onto BaF2(111) substrates. They crystallize in a NaCl‐type structure. The lattice parameter increases asxincreases but not in accordance with Vegard’s law. The optical band gap increases with increasingxvalues. Our data seem to indicate the stability of Eu2+for 0<x<0.55.
