“…This layered microstructure is apparently related to the initial distribution of the Zn and S. The RBS results in Fig. 7 show that the layer of elongated precipitates occurs where the concentration of implanted zinc is greater than ~3.7×10 21 ions/cm 3 . The measured concentration profile of the implanted Zn is significantly wider than would be expected on the basis of TRIM calculations.…”

“…The distribution obtained by TRIM-96 calculations is shown for comparison. The elongated particles occur over an observed depth range corresponding to an implanted Zn concentration greater than approximately 4×10 21 ions/cm 3 . The sulfur distribution is similar to that for zinc but the scatter in the data is considerably larger owing to its low atomic mass Fig.…”

“…During the last decade, several research groups have used ion implantation to synthesize both metallic and semiconductor nanocrystals. In this way, discrete single-element nanoparticles of Cu [17,18], Ag [19][20][21], Au [22][23][24], Fe [25], Pt [26], Pb [27], Se [28], Ge [29], and Si [30][31][32][33] have been formed. Compound nanocrystals have also been formed by sequential implantation of the constituent elements -these include InP [34], GaAs [35,36], ZnS [37,38], CdS [38,39], CdSe [39][40][41] and PbS [38], as well as oxides such as VO 2 [42], V 2 O 3 [43], and ZnAl 2 O 4 [44].…”

Ion implantation is a versatile and powerful technique for producing nanocrystal precipitates embedded in the near-surface region of materials. Radiation effects that occur during the implantation process can lead to complex microstructures and particle size distributions, and in the present work, we focus on the application of these effects to produce novel microstructural properties for insulating or semiconducting nanocrystals formed in optical host materials. Nanocrystal precipitates can be produced in two ways: by irradiation of pure (i.e., non-implanted) crystalline or amorphous materials, or by ion implantation followed by either thermal annealing or subsequent additional irradiation. Different methods for the formation of novel structural relationships between embedded nanocrystals and their hosts have been developed, and the results presented here demonstrate the general flexibility of ion implantation and irradiation techniques for producing unique near-surface nanocomposite microstructures in irradiated host materials.

“…In these materials, the glasses dispersed with noble metal particles, such as gold, silver and copper, are interested in their unique optical absorption in the visible light range due to localized surface plasmon resonance (LSPR) and fast nonlinear optical response time in the order of a few ps [1]. The bulk glasses dispersed with metal particles were prepared by the melt-quenching [1,2] and the ionimplantation [3] method, and in addition, thin films were also prepared by the sol-gel [4][5][6] and the sputtering [7] method. So far, linear and nonlinear optical properties of them have been extensively studied.…”

Nano-sized silver particles generated by the evaporation-condensation method were deposited on the silica glass substrate or sol-gel derived silica film to form films, which were annealed at 100 to 500• C. The surface morphology and optical absorption spectrum of the films thus obtained were observed. Furthermore, nonlinear optical properties of them were estimated using Z -scan technique. Absorption spectrum exhibited a peak due to localized surface plasmon resonance (LSPR), which was drastically shifted toward shorter wavelength side after annealing at 200• C accompanying with the changing of the surface morphology. The nonlinear refractive index, γ, of silver films was negative, and its absolute value was decreased with increasing the annealing temperature. The largest contribution of LSPR resulted in the enhancement of γ when annealed at 100• C.

“…Lithium niobate (LiNbO 3 ) is an important material for integrated and guided-wave optics because of its large pyroelectric, electro-optic and photoelastic coefficients. Several techniques have been employed to fabricate the waveguide on LiNbO 3 crystal such as Ti diffusion (4), proton exchange (5), ion implantation (6)(7)(8) and low-energy ion irradiation (e.g. helium, fluorine, oxygen) with some mega electron volt kinetic energy (9).…”

Single crystals of lithium niobate were irradiated by 50 MeV Li 3+ ion irradiation at various ion fluences. The irradiated single crystals were subjected to various studies such as X-ray diffractometry, UV-VIS-NIR analysis and refractive index measurements. Atomic force microscopy patterns were recorded to study the surface changes after irradiation. Micro-Raman measurements were also recorded for irradiated specimens and the result of the measurements are discussed in detail.
