Abstract
Manganese, a non-rare earth element with a rich variety of oxidation states, is considered as a promising alternative for europium or chromium for the design of red to near-infrared persistent luminescent phosphors.[1] The Mn emission is dominantly determined by its valence, ion distribution and local coordinational environment. Mn4+ ions with 3d3 electron configuration can be stabilized and situated in octahedral symmetry environment of several hosts. Mn4+-doped phosphors usually exhibit both broadband excitation and sharp emission, and their optical properties are strongly influenced by the local crystal field.[1] Currently, it remains a challenge to achieve Mn4+-activated phosphors with long afterglow and strong luminescence intensity compared to traditional Cr3+-doped materials.[2] This problem can be caused by the difficulty to stabilize Mn4+ ions in the host. Three different classes of Mn4+-activated oxides (namely aluminates, germanates and titanates) are investigated and discussed. To introduce appropriate traps and optimize the optical properties, strategies such as compositional modification and codoping are adopted.
