Metal halide double perovskite semiconductors are attracting increasing attention due to their low toxicity and stability compared to lead-containing perovskite semiconductors. In this study, we focused on Cs2AgInCl6 and prepared single-crystal samples with added Cu to improve luminescence efficiency and control the bandgap. We investigated the structural and optical properties under high pressure. High-pressure luminescence measurements revealed that the addition of Cu caused the luminescence peak position to remain almost unchanged even under pressure.
