“…5,6) Thus, it is worthy to study the defects in ion-implanted materials by using inert elements, which have no chemical interaction with ZnO, to exclude the influence of dopants. 7,8) In this regard, Ne is selected as an appropriate implanting element owing to its inert nature and comparable ionic radius with that of Zn and some acceptor dopants such as Na.…”

Unusual vibronic fine structures of the ∼3.0 eV violet emission from ion-implanted ZnO nanorods have been investigated by photoluminescence (PL). A set of equally separated peaks with energy spacing of 72 meV, which corresponds to the longitudinal optical (LO) phonon energy of ZnO, were well resolved in the low-temperature PL spectra. The overall emission band can be perfectly described on the basis of the LO phonon-assisted transition with the Huang–Rhys factor of 1.98, indicating intermediate electron-phonon coupling. The thermal quenching of PL gives rise to an activation energy of ∼160 meV, which is attributed to the energy level of acceptor-like defects introduced by implantation.

“…In conclusion, light restrictions are achieved, for ridge waveguides with width ranging from 20 to 40μm, with proper depth and good modal properties. Compared to previous reports on ZnO waveguides induced by ion implantation [26,27], here the energy leakage can be suppressed effectively, benefiting from proper guiding depth induced by 15 MeV C 5+ ion irradiation, showing good prospects in future applications.…”

“…A few attempts have been made in recent years to introduce the ion implantation method into the fabrication of waveguides in ZnO [26,27]. However serious mode leakage of the ion implanted ZnO waveguides existed, which limited its application in integrated systems.…”

In this work swift-heavy C 5+ ion irradiation with energy of 15 MeV was taken place in ZnO crystal. Planar waveguide is observed in the ion beam affected region, showing single-mode optical confinement for both TE and TM polarization, with propagation loss at a low level. Refractive index profile of the waveguide was reconstructed, showing an optical "barrier" in the ion trajectory. Furthermore, ridge waveguides with good propagation properties were produced by precise diamond blade dicing. This is the first time to our knowledge the formation of 2-dimensional waveguides in ZnO crystal, using ion beam technique. , "Low-loss and directional output ZnO thin-film ridge waveguide random lasers with MgO capped layer," Appl.

“…In addition, ion irradiation induces refractive index changes in the near-surface region of the material through near-physical mechanisms, which makes it generally suitable for waveguide production in substrates. Light ions (e.g., hydrogen or helium ions) have been widely utilized in the preparation of waveguide structures in multiple materials [6,7]. In this case, the waveguide presents a typical barrier refractive index profile due to the lattice damage at the end of the ion range.…”

With valuable physicochemical properties, yttria-stabilized zirconia crystal has promising advantages in optical applications. In this paper, the waveguide effect is observed in yttria-stabilized zirconia crystal irradiated by energetic oxygen ions. The waveguide properties and the field intensity are analyzed using prism and end-face coupling method arrangements, and the results show that monomode is found in the near-surface region and the light beam can be well confined in the waveguide structure, which shows refractive index distribution of the barrier-wall and enhanced-well type. The lattice damage induced by irradiation is investigated by the Rutherford backscattering/channeling experiment and high-resolution X-ray diffraction techniques. The simulation results are in good agreement with the experimental data.
