Abstract

Digenite Cu_1.8S and covellite CuS nanoparticles can both be obtained through the hot-injection synthetic process by controlling the synthesis temperature and time. Compared with digenite Cu_1.8S, covellite CuS attracts more attention due to the extraordinary LSPR effect. However, digenite Cu_1.8S is thermally more stable and suitable for applications at elevated temperature. In this work, LSPR was found to be induced by incorporation of manganese (Mn) into originally weakly absorbing digenite Cu_1.8S nanoparticles. In addition, it was observed that the intensity of the LSPR effect could be controlled by tuning the manganese content in the new Mn-incorporated digenite Cu_1.8S (Cu_xMn_yS) nanoparticles.
