Abstract
We have studied the IR transmission of the EuLnCuS3 (Ln = La, Pr, Sm, Gd) compounds in the spectral range 400 to 4000 cm–1 and their thermal expansion in the temperature range 300–1450 K. The compounds have high IR transmission in the range 1800–3000 cm–1. The observed sharp changes in their thermal expansion coefficients are caused by phase transitions.
