The coupling chemistries that have been widely used in organic chemistry for producing chemical bonds have been applied to form irreversible and stable nanoparticle arrays on surfaces. Eychmriller et al. used the carbodiimide coupling chemistry to covalently assemble carboxylate-functionalized CdTe nanocrystals (NCs) onto amino-terminated glass surfaces, which resulted in densely covered nanoparticle films.14 The same principle was also applied to coat Si02 microparticles by CdTe NCs. 

The temperature dependence of the conductivity behavior of the nanoparticle films predicted that electronic conduction occurred via an electron hopping mechanism.

Figure 19.2 Self-similarity analysis for nanotextured silver surfaces prepared in different ways. The root mean square roughness inferred from atomic force microscopy is plotted versus measurement area. The various surfaces are 100 nm thick evaporated silver films (solid squares, red line)-, 5.2 nm thick evaporated silver films (open circles, green line) nanoparticle films assembled from colloid attachment to self-assembled monolayers (solid circles, blue line) films from deliberate precipitation of silver colloid (solid up-triangles, black line) Tollens reaction films (open down-triangles, orange line). Lines with slopes H = 1.0 and H = l.S representing two-dimensional and 1.5 dimensional surfaces respectively are...

Figure 19.4 (A) Extinction spectra of silver nanoparticle films used for PtOEP emission enhancement. (B) Corresponding excitaticm spectra monitored at 650 mm of 6 nm films of PtOEP in a polystyrene binder spin cast onto the silver films. (C) Excited state decay dynamics of the PtOEP phosphorescence for 6 nm films excited by S ns pulses at 332 nm with no silver (c) and on substrates like number 4 from A with silver coverage to optimize enhancement (b). The instrument resolution when detecting scattering of the excitation pulse (a) is shown for reference. Reprinted from reference 43 with permission of the American Chemical Society.
