Abstract

A series of luminescent rare-earth ion-doped hexagonal II-type Gd oxycarbonate phosphors Gd_2-xRE_xO₂CO₃ (RE = Eu³⁺, Yb³⁺, Dy³⁺) have been successfully synthesized by thermal decomposition of the corresponding mixed oxalates. The Yb³⁺ doped Gd-oxycarbonate has evidenced a high persistent luminescence in the NIR region, that is independent from the temperature and makes this materials particular attractive as optical probes for bioimaging.
