Persistent Photochemical Hole-Burning in the R‑Lines of Tetravalent Manganese in Submicron α‑Al2O3

Persistent spectral hole-burning in the R-lines of tetravalent manganese in X-irradiated submicron corundum powder is reported for the first time. Two samples were investigated, namely, nominally 0.4 atom % Mn3+-doped and 0.4 atom % Mn4+, Mg2+-codoped α-Al2O3. The samples were produced by a simple c...
