Na. Kotov et al., LAYER-BY-LAYER SELF-ASSEMBLY OF POLYELECTROLYTE-SEMICONDUCTOR NANOPARTICLE COMPOSITE FILMS, Journal of physical chemistry, 99(35), 1995, pp. 13065-13069
Spectroscopic (absorption and emission), microscopic (transmission ele
ctron and atomic force), X-ray diffraction and photocurrent measuremen
ts have provided evidence for the formation of stable ultrathin films
with regular periodicities, by the layer-by-layer self-assembly of pol
ycations and cadmium sulfide, lead sulfide and titanium dioxide nanopa
rticles.
