A nanostructured willemite doped with manganese (Zn2SiO4:Mn2+) was synthesized by sol-gel method followed by high-temperature annealing. Prepared Zn2SiO4:Mn2+ is characterized by average particle size of 100 nm, narrow particle size distribution, and high crystallinity. Under UV-excitation nanostructured willemite shows an intensive photoluminescence at 520 nm corresponded to activator Mn2+ emission. It was found that the emission decay curves of willemite becomes non-exponential with increasing of manganese content. Zn2SiO4:Mn2+ reveals long-lasting phosphorescence up to 45 ms. Absolute quantum yield of Zn2SiO4:Mn2+ reaches 47 % at 0.1 at. % of Mn2+. The luminescence concentration quenching effect at Mn2+ concentration higher than 1 at % is observed.
