Abstract
Compositions for deposition of ultrathin layers of nanoparticle films are provided. Ultrathin nanoparticle films and methods for deposition thereof involving applying the nanoparticle-metal alkoxide solution to a substrate, such that a formed metal oxide is anchored on a surface of the substrate to form an ultrathin nanoparticle film are also provided.
Claims20
A composition comprising nanoparticles dispersed in a metal alkoxide solution, wherein the metal alkoxide solution comprises a transition metal alkoxide precursor and an anhydrous solvent, wherein the transition metal alkoxide precursor is in a predetermined amount to anchor a formed metal oxide on a surface of a substrate and to form a nanoparticle film, wherein the predetermined amount of the transition metal alkoxide precursor is between 5% and 90% by volume.
A method for forming a nanoparticle film, said method comprising:
- preparing a metal alkoxide solution comprising a predetermined amount of a transition metal alkoxide precursor in a solvent,
- wherein the predetermined amount of the transition metal alkoxide precursor is between 5% and 90% by volume;
- mixing pre-dried nanoparticles with the metal alkoxide solution to obtain a nanoparticle-metal alkoxide solution;
- and
- applying the nanoparticle-metal alkoxide solution to a substrate, such that a formed metal oxide is anchored on a surface of the substrate, thereby forming a nanoparticle film.
