Abstract

In this study, we synthesized the chalcogenide glass($Ge_{19}Sb_{23}Se_{58}$) for infrared optics by meltquenching method and verified the effect of cooling condition on the glass properties. The structural and optical properties of the glass were analyzed by XRD, FT-IR and SEM image. The glass synthesized under the cooling temperature of $980^{\circ}C$ shows transmittance of 58% at $8\sim12{\mu}m$, which was decreased as the cooling temperature was decreased. In addition, thermal and hardness also were measured. From the analysis results, we ascertained the feasibility as a molding materials for infrared optics.
