Excitation energy-dependent photoluminescence behavior in Zn2SiO4:Mn phosphors

Luminescent silicate core–shell nanoparticles: Synthesis, functionalization, optical, and structural properties

“…A slight non-exponentiality of the decay in the 5 mol% sample gives evidence of concentration quenching. According to Inoue et al [38] and Sohn et al [39], the quenching starts at 6-7 mol%; it is possible that the inhomogeneous distribution of Mn 2+ ions in our samples leads to quenching at lower concentrations. A much stronger quenching effect is seen in the samples doped nominally with 20 mol%.…”

Photoluminescece and Thermoluminescence Behavior of Zn2SiO4: Mn2+, Eu2+ Phosphor

“…Transition and rare-earth ions are excellent luminescent centers as a result of their inner shell electronic transitions. Consequently, transition and rare-earth ion doped zinc silicates have been studied extensively as efficient luminescent materials (Sohn et al, 1999;Zhang et al, 2001;Selomulya et al, 2003;Taghaviniaa et al, 2002;Wang et al, 2003;Reinhard et al, 2004). Mn 2+ doped Zn2SiO4 phosphors emit green light when excited by UV light or cathode rays.…”
