Review of research articles reveals the production of nanomaterials by low temperature Sol-Gel Synthesis is a simple process. Few are described from available reports.

InAs nanocrystals by Sol-Gel Synthesis
III-V semiconductor nanocrystals rarely exist as spherical inclusions inside glasses. This III-V semiconductor InAs nanocrystals have been made by sol-gel synthesis. Gels were synthesized by the hydrolysis of a complex solution of Si(OC2H5)4, InCl3 x 4H2O, and As2O3. The gels were then heated at 200-450 degrees C in the presence of H2 gas to form fine cubic InAs crystallites. Size of InAs nanocrystals was found to be from 5 to 30 nm in diameter. A strong room temperature photoluminescence was observed from InAs nanocrystals embedded in silica glasses.

Similarly sol-gel synthesis of luminescent InP nanocrystals embedded in silica glasses was done as fallows. Gels were synthesized by hydrolysis of a complex solution of Si(OC2H5)4, InCl3.4H2O, and PO(OC2H5)3. Then, the gels were heated at 600 degrees C in the presence of H2 gas to form fine cubic InP crystallites. The size of InP nanocrystals was found to be from 2 to 8 nm in diameter. A strong photoluminescence was observed from InP nanocrystals embedded in silica glasses.
Li2TiO3 nanopowder by Sol-Gel Synthesis
High purity and nano-sized Li2TiO3 powder was synthesized by a newly developed sol-gel method using water as the reaction medium and LiNO3 and Ti(C6H6O7)2 as raw materials at the temperature as low as 500 °C. Particle size of the obtained powder was as small as 40 nm. The powder possessed excellent sinterability, exhibiting a linear shrinkage of 14% while sintered to 1200 °C. The sintered pellets fabricated from the powder at 1100 °C for 4 h reached a density as high as 90% T.D. The process developed in this work was simple and convenient to realize mass production.
