Structural and luminescent properties of silicon nanoparticles incorporated into zirconia matrix

Raman amplification in nanoparticles doped glasses

“…Recent work by Klangsin et al [11] on Si nanoparticles within ZrO 2 matrix showed the influence of the matrix properties on the nanoparticles. From Raman analysis and TEM measurements, they observed a shift of the nanoparticles Raman bands which are related to stress effects and then to the contact between the nanoparticles and the matrix.…”

Thermal Properties of Porous Silicon

“…At the final steps, prepared PSi nanoparticles can be suspended in a solvent (like ethanol, hexane), filtered or centrifugated in order to obtain the desired size distribution, and then eventually can be deposited on a substrate, mixed with other substances, or incorporated into different dielectric or polymer matrices (Švrček et al 2002Klangsin et al 2008;Zhang et al 2014). The process of PSi nanoparticle incorporation in polymer matrix, designed by Zhang et al (2014), is shown in Figure 12.33.…”

Influence of the dielectric matrix on photoluminescence and energy exchange in ensembles of silicon nanocrystals

“…In addition to the classical, well studied system SiO 2 :nc Si, Si nanocrystals were obtained by various methods in Si 3 N 4 matrices [1] and in promising dielectric matrices with high static permittivity ε, namely, Al 2 O 3 [2] and ZrO 2 [3]. Dielectrics with high ε can be used as subgate dielectrics in multilayer struc tures with Si nanocrystals [4] or in memory elements based on Si quantum dots [5].…”

“…Dielectrics with high ε can be used as subgate dielectrics in multilayer struc tures with Si nanocrystals [4] or in memory elements based on Si quantum dots [5]. In addition, they are regarded as dielectrics that can be used instead of SiO 2 in light emitting diodes based on Si nanocrystals [2,3].…”
