Green-emissive textured Zn2SiO4:Mn2+ phosphor film was fabricated by a thermal diffusion of ZnO:Mn on
quartz glass. The characterization has been performed in terms of Mn2+ ions concentration (Mn/Zn=1~9 mol %). As an
increase of Mn2+ ions concentration in the Zn2SiO4:Mn2+ phosphor film, the emission peak was red shifted from 519 nm
to 526 nm, and the decay time to 10% of the maximum intensity was shorter from 20 ms to 0.5 ms. All annealed
Zn2SiO4:Mn2+
phosphor films became textured along some hexagonal directions on the amorphous quartz glass. The
brightest Zn2SiO4:Mn2+
film at optimal Mn2+ concentration of 5 % showed the photoluminescence brightness of 65 %
and the shortened decay time of 4.4 ms in comparison with a commercially Zn2SiO4: Mn2+ powder phosphor screen. The
excellencies can be attributed to a unique textured structure.
