摘　　要：We present first principles calculations of optical properties of binary semiconductor compounds TlBr and TlCl.Dependences of dielectric function,reflectivity and refractive index on hydrostatic pressure are calculated using self-consistent scalar relativistic full potential linear augmented plane wave method(FP-LAPW) within a generalized gradient approximation(GGA).They are compared with previous calculations and experimental measurements.Good agreements are found.We present first principles calculations of optical properties of binary semiconductor compounds T1Br and T1C1. Dependences of dielectric function, reflectivity and refractive index on hydrostatic pressure are calculated using self-consistent scalar relativistic full potential linear augmented plane wave method （FP-LAPW） within a generalized gradient approximation （GGA）. They are compared with previous calculations and experimental measurements. Good agreements are found.
