O5+-ion irradiated ridge waveguide operating at mid-infrared wavelength in ZnS crystal

Yazhou Cheng et al.

Summary: A ridge waveguide for single-mode transmission at the mid-infrared wavelength of 4 μm is fabricated using O5+-ion irradiation and diamond-blade dicing techniques in a zinc sulfide crystal. The refractive index distribution of the waveguide is well-modeled, and experimental results confirm its accuracy. After annealing treatment, the propagation loss of the ridge waveguide is reduced to 0.4 dB/cm for the TE mode. Analysis of Raman spectra shows no significant lattice damage in the modified region after O5+-ion irradiation in ZnS crystal.

Concentric core-shell tracks and spectroscopic properties of SrTiO3 under intense electronic excitation

Xinqing Han et al.

Summary: This study comparatively analyzed the structural damage response, spectroscopic features, and physical mechanisms of SrTiO3 single crystals under swift heavy ion irradiation using experimental and theoretical approaches. The study identified the dominant effects of deposition energy and lattice temperature on track damage formation and evolution, and proposed two essential thresholds to describe the concentric core-shell track structure. The study also revealed the combined action of kinetic and potential energy depositions in the enhanced nanohillock formation and the fluence dependence in regulating hillock dimensions. Additionally, the study observed the anisotropy of irradiation-induced lattice expansion and the decrease of intrinsic bandgap with increasing ion fluence and damage level, which provides the possibility of regulating related defects for technological applications.

Enhanced Raman intensity in ZnS planar and channel waveguide structures via carbon ion implantation

Tao Liu et al.

Summary: The fabrication of planar and channel waveguides in ZnS single crystal using 6.0 MeV C ion implantation at room temperature is studied. Optical modes are measured using prism coupler and near-field light intensity profiles are measured at different wavelengths. Reflectivity calculation method and finite difference beam propagation method are used for reconstructing refractive index profiles and near-field intensity distributions. Raman images obtained with a 532-nm laser are used to evaluate damage to the crystal and waveguide layers.

Ethanol sensor using gadolinia-doped ceria solid electrolyte and double perovskite structure sensing material

Tong Liu et al.

Summary: Gas sensors based on mixed potential gadolinia-doped ceria (GDC) using a double perovskite composite oxide (Sr2NiMoO6) were fabricated to detect ethanol, with the material annealed at 1000 degrees C showing the highest sensitivity in the range of 1-200 ppm. The sensor response value Delta V was piecewise linear with the logarithm of ethanol concentration, with the slopes of -8 and -51.3 mV/decade for 1-10 ppm and 10-200 ppm ethanol, respectively. Stability and sensing mechanism of the sensor were also investigated.
