“…Therefore, the combination of plasmonic structures and lithium niobate opens a wide range of new applications; one example is the increase of nonlinear refractive indices due to the incorporation of metal clusters [5]. Because of their surface plasmon resonance (SPR) located in the visible spectral range [5][6][7][8] and their resistivity to oxidation, noble metals, especially silver, are widely used for cluster formation in lithium niobate. A very versatile and therefore well-established method for the synthesis of embedded clusters is ion implantation.…”

Spherical silver nanoparticles were prepared by means of ion beam synthesis in lithium niobate. The embedded nanoparticles were then irradiated with energetic (84)Kr and (197)Au ions, resulting in different electronic energy losses between 8.1 and 27.5 keV nm(-1) in the top layer of the samples. Due to the high electronic energy losses of the irradiating ions, molten ion tracks are formed inside the lithium niobate in which the elongated Ag nanoparticles are formed. This process is strongly dependent on the initial particle size and leads to a broad aspect ratio distribution. Extinction spectra of the samples feature the extinction maximum with shoulders on either side. While the maximum is caused by numerous remaining spherical nanoparticles, the shoulders can be attributed to elongated particles. The latter could be verified by COMSOL simulations. The extinction spectra are thus a superposition of the spectra of all individual particles.

“…Thus, cluster ion implantation can be regarded as a forerunner technology as compared with the conventional ion implantation technique used to dope sub-micrometre devices [13,15]. Recently, low energy cluster ions (60 keV Au − 2 ) has also been utilized successfully to synthesize Au NPs embedded in SiO 2 [16].…”

The effects of annealing atmosphere (argon or oxygen) on Zn nanoparticles (NPs), embedded in silica glass, synthesized by implanting 50 keV ZnO− ions to a fluence of 7 × 1016 cm−2 have been studied. Optical absorption (OA) measurements carried out on the as-implanted samples have been found to result in a surface plasmon resonance (SPR) band centred at ∼255 nm due to the presence of Zn NPs in the silica glass. An increase in SPR peak intensity with a corresponding reduction of its full width at half maximum have been seen in the OA spectrum taken from the as-implanted sample following annealing in Ar ambient at 700 °C for 2 h, indicating a growth in the size of Zn NPs. However, annealing the as-implanted sample in O2 gas at 700 °C for 2 h has been found to result in a steep absorption edge at ∼364 nm in the OA spectrum which indicates the formation of ZnO NPs. These ZnO NPs show quantum confinement effects due to their small sizes. No observable photoluminescence (PL) emission has been seen from Zn NPs, whereas an excitonic band at ∼368 nm and three deep-level PL emission bands at ∼453 nm, ∼521 nm and ∼650 nm, respectively, have been seen from ZnO NPs. It was argued that the deep-level PLs were due to the singly ionized oxygen vacancies located at ZnO NPs' surfaces. These observations suggest that ZnO NPs were formed due to oxidation of Zn NPs via interaction with the indiffusing O2 molecules during annealing in O2 ambient, but not with the interaction of the implanted oxygen in silica glass.
