One-Step Synthesis for Zn₂SiO₄:Mn Particles 0.3–1.3 µm in Size with Spherical Morphology and Non-Aggregation

Abstract

Particles of the green luminescent Zn 2 SiO 4 :Mn having size of 0.3–1.3 µm was directly prepared by spray pyrolysis without post-annealing processes. Characteristics of as-prepared particles such as crystallinity, morphology, and photoluminescence were investigated. Zn 2 SiO 4 :Mn particles with spherical morphology, non-aggregation, and having pure willemite was formed at a temperature of 1000–1300°C. The luminescence of the Mn 2+ ion in Zn 2 SiO 4 shows an emission band in the 525 nm when excited by 254 nm light.
