| Abstract: | Eu-doped silicate complex gel nano-particles was obtained by sol-gel process and characterized with TEM, XRD, PL, etc. The well dispersed particles have particle size about 60～70 nm with specific surface area 98.3 m2·g-1. The complex gel phosphor gives a broad and strong luminescent emission originating from Eu2 ions centered at 425 nm. The emission band shifts to shorter wavelengths with the increase of the ion radius of the alkali earth metals, but the band becomes red-shifted gradually with the increase of the ion radius of the alkali metals(except Li ). These divalent Eu2 ions originate in inequivalent substitution of the alkaline earth ions. The presence of alkaline ions is favorable for the increasing emission intensity of the Eu2 and lowering crystalline temperature of the silicate complex gel. |
