Germanenko et al. [153] suggested an explosive detector based on the photolumines-cence of silicon nanostructures. Silicon nanocrystals are first prepared by laser vaporization (LVCC). After suspension in methanol, the silicon nanocrstyals are excited by a laser at 355 nm, resulting in photoluminescence. They found that nitrotoluenes quench the photoluminescence from the silicon nanocrystals. Quenching rate constants for a number of nitro-compounds were presented. [Pg.316]

Here, the PL is shifted to the blue region where PL from heavily oxidized PS and nc-Si has been reported [19, 30-32]. For curiosity and to illustrate that photoluminescence is a very common phenomenon in organosilanes we show in Fig. 1 also the PL measured from silicone vacuum grease [29]. We shall return to this point later on. [Pg.825]

Figure 23.5. Mechanism of photoluminescence from nc-Si/Si02 nanocomposites Left pictorial illustration, right energy levels involved in (1) the photogeneration of electron-hole pairs in the silicon nanocrystals, the band gap and transition probabilities of which increase with decreasing crystallite size, which is followed by an energy transfer to localized radiative centers, such as (2) a non-bridging oxygen hole center (NBOHC) in the Si02 layer or (2 ) a metallic impurity.

The mechanism of the photoluminescence from nc-Si/Si02 nanocomposites includes a quantum confinement controlled photogeneration of electron-hole pairs within the silicon nanocrystals, followed by an energy transfer to nonbridging oxygen hole centers within the passivating Si02 matrix. The relatively inefficient and slow PL from such radiative centers is of little interest. A variety of other PL that have been reported in the literature and attributed to radiative recombination within the Si nanocrystals are most probably due to impurities. Several examples are shown to illustrate that extreme care has to be taken in order to avoid such artefacts. [Pg.318]
