Abstract: This study presents the synthesis and characterization of luminescent nanocomposite coatings and gas-based emission systems designed to enhance safety in medium-voltage (MV) power networks. Semiconductor quantum dots, including Si, ZnO, and ZnS, along with europium-doped upconversion particles, were engineered for electric-field-induced optical response. Their emission behaviors were systematically evaluated using UV-Vis, photoluminescence spectroscopy, and electron microscopy. Despite limited fluorescence in coated sensors under MV conditions, gas-filled cells, especially those containing neon, demonstrated robust and visible emissions under high-frequency excitation. The findings underscore the potential of integrating optical nanomaterials and gas-based technologies for real-time visual hazard detection in MV environments.
