Special Issue Information

Dear Colleagues,

Nanophotonics is now a rapidly growing interdisciplinary field of science, mainly due to the unique properties of optical waveguide nanostructures, obtained as a result of their interaction with photons. The most advanced systems are found in the currently used waveguide nanostructures, characterized by sophisticated optical properties and excellent thermal stability parameters required in modern nanomaterials. Therefore, the construction of such materials requires an interdisciplinary approach to combine fields of materials engineering and photonics.

One of the current directions of research in modern photonics is functional nanomaterials with luminescent and structural properties enabling the construction of new structures to be applied in integrated systems, precise sensors, optical memories, and medical applications. Therefore, particular attention is paid to creating different nanomaterials, such as noble metals nanoparticles, nanocrystals, nanorods, nanoceramics, etc., which can influence the luminescent properties of lanthanide ions and enable one to obtain new functional nanostructures.

This Special Issue of Nanomaterials focuses on fundamental nanostructured materials, nanocomposites glass and ceramics, and their luminescent and structural properties for photonic applications.

Laser direct writing technique in glass is a powerful tool for various waveguides’ fabrication that highly develop the element base for designing photonic devices. We apply this technique to fabricate waveguides in porous glass (PG). Nanoporous optical materials for the inscription can elevate the sensing ability of such waveguides to higher standards. The waveguides were fabricated by a single-scan approach with femtosecond laser pulses in the densification mode, which resulted in the formation of a core and cladding. Experimental studies revealed three types of waveguides and quantified the refractive index contrast (up to Δn = 1.2·10−2) accompanied with ~1.2 dB/cm insertion losses. The waveguides demonstrated the sensitivity to small objects captured by the nanoporous framework. We noticed that the deposited ethanol molecules (3 µL) on the PG surface influence the waveguide optical properties indicating the penetration of the molecule to its cladding. Continuous monitoring of the output near field intensity distribution allowed us to determine the response time (6 s) of the waveguide buried at 400 µm below the glass surface. We found that the minimum distinguishable change of the refractive index contrast is 2 × 10−4. The results obtained pave the way to consider the waveguides inscribed into PG as primary transducers for sensor applications. Full article

Antimony selenide (Sb2Se3) has been widely investigated as a promising absorber material for photovoltaic devices. However, low open-circuit voltage (Voc) limits the power conversion efficiency (PCE) of Sb2Se3-based cells, largely due to the low-charge carrier density. Herein, high-quality n-type (Tellurium) Te-doped Sb2Se3 thin films were successfully prepared using a homemade target via magnetron sputtering. The Te atoms were expected to be inserted in the spacing of (Sb4Se6)n ribbons based on increased lattice parameters in this study. Moreover, the thin film was found to possess a narrow and direct band gap of approximately 1.27 eV, appropriate for harvesting the solar energy. It was found that the photoelectric performance is related to not only the quality of films but also the preferred growth orientation. The Te-Sb2Se3 film annealed at 325 °C showed a maximum photocurrent density of 1.91 mA/cm2 with a light intensity of 10.5 mW/cm2 at a bias of 1.4 V. The fast response and recovery speed confirms the great potential of these films as excellent photodetectors. Full article
