Abstract The silica sols of particle size 20--100 nm were prepared using tetraethyl silicate as precursor. The porous silica antireflective coatings were prepared on the glass by the dip-coating method. The microstructure of sol particles with different particle size after aging and their influence on porous silica antireflective coating were investigated. Results show that the small silica colloid particles with size -20 nm reunit into large secondary particles during the aging process. The antireflective coating prepared of secondary particles has the desired loose structure and the peak transmittance of glass with the antireflective coating reaches 99.2% at 510 nm.
