“…However, with further increase in the bombardment energy, more Ag particles were implanted into the deeper position, while the Ag particle concentration in the Mo substrate surface decreased. This is consistent with some previous reports [ 40 , 41 ]. Therefore, for the immiscible feature of Ag-Mo system, the inter-atomic mechanical interlocking between the films and the substrate would been weaken due to the reduction of the Ag concentration in the surface of the substrate, causing the adhesive strength decrease.…”

Silver-coated molybdenum is an optimum material selection to replace pure silver as solar cell interconnector. However, the low adhesive strength between Ag films and Mo substrate hinders the application of the interconnector, because it is difficult to form metallurgical bonding or compound in the film/substrate interface using conventional deposition. In order to improve the adhesion, some Ag particles were implanted into the surface of Mo substrate by ion beam-assisted deposition (IBAD) before the Ag films were deposited by magnetron sputtering deposition (MD). The objective of this work was to investigate the effect of different assisted ion beam energy on the film/substrate adhesive properties. In addition, the fundamental adhesion mechanism was illustrated. The results revealed that the adhesion between Ag films and Mo substrate could be greatly enhanced by IBAD. With the increase of the assisting ion beam energy, the adhesive strength first increased and then decreased, with the optimum adhesion being able to rise to 25.29 MPa when the energy of the assisting ion beam was 30 keV. It could be inferred that the combination of “intermixing layer” and “implanted layer” formed by the high-energy ion bombardment was the key to enhancing the adhesion between Ag films and Mo substrate effectively.

“…Unlike the above-mentioned transition metal ion implantation, Tsuji and his co-workers [12,13] have implanted negative ions of silver into both rutile and anatase titania films to test their visible light sensitivity, and positive results were also obtained. The silver is categorized to the noble metal group which is different from the above-mentioned transition metal group in the method of doping.…”

The electronic structures of Ag-doped rutile and anatase TiO2 are studied by first-principles band calculations based on density functional theory with the full-potential linearized-augmented-plane-wave method. New occupied bands are found between the band gaps of both Ag-doped rutile and anatase TiO2. The formation of these new bands can be explained mainly by their orbitals of Ag 4d states mixed with Ti 3d states and are supposed to contribute to their visible light absorption.

“…One of the main obstacles is the low photocatalytic efficiency. [ 6,170–174 ] Metallic NPs have shown great potential to accelerate the photocatalysis process by hot electron transfer mechanism, and embedding NPs in photocatalytic materials by ion implantation leads to an enhanced interaction between NPs and dielectrics for further improvement of photocatalysis. As depicted in Figure , Hou et al reported the enhancement of catalytic activity in Ag NPs–TiO 2 nanocomposite by ion implantation.…”

The zero‐dimensional metallic nanoparticles (NPs) have attracted tremendous attention in various areas owing to the collective oscillation of electron gas that couples with electromagnetic field, known as localized surface plasmon resonance (LSPR). In practical applications, the tailoring of LSPR effect is of significant importance for promising photonic devices with designed nanocomposite systems and enhanced optical properties. Ion beam technology has been demonstrated to be an efficient method to fabricate NPs embedded in dielectrics for LSPR tailoring and material modification. By manipulating the parameters of ion beams, the shape, size, and structure of NPs can be well controlled, which enables the dielectrics to possess novel linear and nonlinear optical properties. In this review, the latest research progress on the ion beam synthesis of various NPs is systematically summarized. The tailoring of linear and nonlinear optical properties of dielectrics by NPs is discussed in detail. Selected applications are presented to indicate the development of the plasmonic NPs in dielectric systems for photonic applications.
