N2 - We fabricated Mn2+-activated nanocrystallized glasses (NCG) with willemite-type Zn2GeO4 from a zincogermanate system glass added by various MnO-concentrations, and examined their photoluminescence (PL) properties. The Mn2+-activated NCGs indicated bright green-emission based on the 4T1→6A1 transition of the Mn2+, indicating exclusive Mn2+-occupation of Zn site in the Zn2GeO4 nanocrystals. In addition, green long-lasting photoluminescence (LLP) was also observed in the NCGs with low MnO-concentration. Relation between the MnO-concentration and the LLP property was also considered.
