Manavbasi, J. LaCombe] Green light emitting Zn2−x Mn x SiO4 (willemite) particles were synthesized by a simple and cost-effective poly(vinyl alcohol) (PVA)-complex route. Microstructural studies on the calcined products show that particles are pure, single phase, nano-crystalline, and agglomerated morphology. A pure-phase willemite structure was obtained with calcination between 850 and 1,175°C for 2h in air. Particle size analysis indicates that the average particle size is ∼1μm. The photoluminescence properties of these 4 and 12mol% Mn-doped Zn2SiO4 powders were measured by fluorescence spectroscopy. Particles with 4mol% Mn doping prepared at 1,150°C, with an emission decay time, I 0/e, of 13.4ms showed the highest relative peak emission intensities. The emission intensity at this doping level was measured to be ∼110% of a representative commercial product's, doped with 11.2mol% Mn, and exhibiting a decay time of 7.1ms. The effect of calcination temperature on the photoluminescence and crystallinity properties of synthesized green powders was also investigated. Springer Science+Business Media, LLC, 2006 Manavbasi A.
