Summary: The study utilized an all-fiber fluorescence intensity ratio (FIR) optical thermometer to detect hydrogen concentration by measuring the local environmental temperature change. Temperature sensing optical material was synthesized and used to develop a temperature sensing probe, achieving maximum absolute temperature sensitivity and error values at different temperatures. Furthermore, the relationship between H2 concentration and temperature change was established through the reaction of H2 with Pt-loaded film, laying the groundwork for detecting H2 gas leaks during transportation and storage.

Summary: A simple optical fiber temperature sensing system based on up-conversion luminescence of Er3+/Yb3+ co-doped Gd2O3 phosphors is proposed and demonstrated for the first time. The system utilizes a sandwich structure sensing probe fabricated by two fiber connectors, with the fluorescent material cured with ultraviolet adhesive on the surface. The temperature measurement is achieved by analyzing the fluorescence intensity ratio (FIR) of the two green emissions generated by Gd2O3: 1 mol% Er3+, 1 mol% Yb3+ phosphors.

Summary: This article presents a DNA-stabilized silver nanocluster (DNA-AgNC) with dual emission in the red and near-infrared regions. Mass spectrometry data shows that two DNA strands stabilize 18 silver atoms with a nanocluster charge of 12+. Steady-state and time-resolved methods were used to characterize the red fluorescence and NIR luminescence, and the luminescence-to-fluorescence ratio was found to be excitation-intensity-dependent, making it a nanoscale excitation intensity probe.

Summary: The fluorescence-based temperature measurement technology using rare earth doped NaBiF4 matrix luminescent materials has attracted great interest. However, most current works rely on the thermal coupling energy levels obtained from a single luminous center in the NaBiF4 matrix, limiting the sensitivity and accuracy of temperature measuring materials. In this study, Yb3+/Er3+/Tm3+ triple doped NaBiF4 nanomaterials are prepared and the Arrhenius equation is used to overcome the energy gap restriction and improve the temperature sensitivity and uncertainty. The crystal structure, morphology, photoluminescence properties, and energy transfer of the doped nanomaterials are evaluated, providing insights into integrating them into optical thermometric materials using FIR technology.
