The energy gap and the refractive index of a new quaternary semiconductor material Pb_<1-x>Mn_xS_<1-y>Se_y are determined experimentally. The compositional and temperature dependence of the energy gap of this material is E (x, y, T)=3.93x-0.186y-17.3x^2+0.0373y^2+xy+0.271+(4×10^4+2.65×10^<-7>T^2)^<1/2> (eV). The refractive index decreases as the manganese content increases, and increases with the selenium content. It becomes evident that this new quaternary solid solution is a suitable material lattice-matched to PbS for the confinement layers of double-heterostructure lasers.
