Special Issue Information

Dear Colleagues,

Research on nano-optical systems is introducing innovations into science, technologies, and allows the fabrication of new devices covering a very broad spectrum of applications that influence socio-economic challenges in many fields, going from energy to efficient photons management, from environmental protection to novel integrated communication systems, and from structural monitoring to quantum technologies and healthcare applications.

This Special Issue is focused on nano-optics systems and we invite you to submit your contributions. The general idea is to collect impressive papers devoted to physical, chemical, and hybrid fabrication techniques; the design of innovative nano-optic systems; the modeling and simulation of physical and chemical mechanisms and properties; and the theory behind nanostructured optical systems.

Concerning spectroscopic, optical, morphological, and structural characterizations, we expect scientific papers employing diagnostic techniques covering photoluminescence, time resolved spectroscopy, Raman, AFM, TEM, SEM, XPS, neutron scattering, synchrotron radiation-based technologies, DTA, thermodynamic analysis, and more. Emphasis is expected to be on new physical and chemical properties. Technical articles looking at novel diagnostics, designs and fabrication of components and devices are also welcome.

The objective of this Special Issue is to gather the experiences of leading scientists, and also to be a guide for people who needs to confront non-conventional and emerging routes for the development of nano-optical systems for advanced optical applications. From this point of view, we believe that the Special Issue will provide technological advances, and the latest research on the state-of-the-art in innovative processing and device applications of new materials to meet the challenges of sustainable energy and optical nanotechnologies. Interested and committed individuals from academia, national laboratories, industries, and start-up companies are invited to contribute by submitting papers on the following and related topics:

Spectroscopic Properties of Erbium-Doped Oxyfluoride Phospho-Tellurite Glass and Transparent Glass-Ceramic Containing BaF2 Nanocrystals

Abstract
The ErF3-doped oxyfluoride phospho-tellurite glasses in the (40-x) TeO2-10P2O5-45 (BaF2-ZnF2) -5Na2O-xErF3 system (where x = 0.25, 0.50, 0.75, 1.00, and 1.25 mol%) have been prepared by the conventional [...] Read more.
The ErF3-doped oxyfluoride phospho-tellurite glasses in the (40-x) TeO2-10P2O5-45 (BaF2-ZnF2) -5Na2O-xErF3 system (where x = 0.25, 0.50, 0.75, 1.00, and 1.25 mol%) have been prepared by the conventional melt-quenching method. The effect of erbium trifluoride addition on thermal, structure, and spectroscopic properties of oxyfluoride phospho-tellurite precursor glass was studied by differential scanning calorimetry (DSC), Fourier-transform infrared (FTIR), and Raman spectroscopy as well as emission measurements, respectively. The DSC curves were used to investigate characteristic temperatures and thermal stability of the precursor glass doped with varying content of ErF3. FTIR and Raman spectra were introduced to characterize the evolution of structure and phonon energy of the glasses. It was found that the addition of ErF3 up to 1.25 mol% into the chemical composition of phospho-tellurite precursor glass enhanced 2.7 µm emission and upconversion. By controlled heat-treatment process of the host glass doped with the highest content of erbium trifluoride (1.25 mol%), transparent erbium-doped phospho-tellurite glass-ceramic (GC) was obtained. X-ray diffraction analysis confirmed the presence of BaF2 nanocrystals with the average 16 nm diameter in a glass matrix. Moreover, MIR, NIR, and UC emissions of the glass-ceramic were discussed in detail and compared to the spectroscopic properties of the glass doped with 1.25 mol% of ErF3 (the base glass).

An accelerated thermal aging process was used to simulate the condition of paper insulation in transformer oil-paper systems. Optical parameters of the insulation paper after various aging intervals were analyzed with terahertz time-domain spectroscopy (THz-TDS) over the range 0.1~1.8 THz. The result shows that the paper had seven absorption peaks at 0.19, 0.49, 0.82, 1.19, 1.43, 1.53, and 1.74 THz, and density functional theory of B3LYP/6-311G+ (d, p) was used to simulate the molecular dynamics of the repeating component (cellobiose) of the cellulose paper. Theoretical spectra were consistent with experiment, which had absorption peaks at 0.18, 0.82, 1.47, and 1.53 THz in the same frequency range. At the same time, the paper samples after various aging intervals had different refractive indexes, and least squares fitting revealed a linear relationship between the degree of polymerization and the refractive index of the paper. Hence, this paper demonstrates that THz-TDS could be used to analyze the aging condition of transformer insulation paper and provides the theoretical and experimental basis for detection.
