Abstract

The HPTS serves as a versatile tool in pH and CO2 sensing studies, as well as in cell biology studies of various processes. However, the long-term photostability of HPTS as a fluorescent dye is an important consideration in its use, especially for long-term applications. In this work, sol–gel synthesized Er³⁺, Tb³⁺ and Er³⁺: Tb³⁺ co-doped 1393 bioactive glass particles were incorporated with the HPTS in the presence of ionic liquid in an ethyl cellulose matrix. The interaction of the bioactive glasses with the HPTS was investigated by steady-state luminescence and excited-state lifetime measurements. The prepared composites showed linearizable responses when exposed to different CO₂ concentrations. High I₀/I₁₀₀ values (87, 109 and 115) were obtained for the binary blends of HPTS and bioactive glasses. When the imidazolium-based IL was used together with the offered composites, we observed improved stability and longevity for the HPTS up to 315 days. The incorporation of imidazolium-based ionic liquids as additives in HPTS-based fluorescence assays together with the bioactive glasses holds promise for enhancing the photostability of the HPTS and improving the reliability and longevity of fluorescence signals in various research applications.

基于发射的 Er3+、Tb3+ 和 Er3+-Tb3+ 共掺 1393 生物活性玻璃与 HPTS 对二氧化碳的响应

HPTS 是 pH 和 CO2 传感研究以及各种过程的细胞生物学研究的多功能工具。然而，作为一种荧光染料，HPTS 的长期光稳定性是其使用中的一个重要考虑因素，尤其是在长期应用中。在这项工作中，溶胶凝胶合成了 Er3+、Tb3+ 和 Er3+：Tb3+ 共掺杂的 1393 生物活性玻璃颗粒与 HPTS 在乙基纤维素基质中的离子液体存在下结合在一起。通过稳态发光和激发态寿命测量研究了生物活性玻璃与 HPTS 的相互作用。所制备的复合材料在暴露于不同浓度的二氧化碳时表现出线性响应。HPTS 和生物活性玻璃的二元共混物获得了较高的 I0/I100 值（87、109 和 115）。当咪唑基 IL 与所提供的复合材料一起使用时，我们观察到 HPTS 的稳定性和寿命都有所提高，最长可达 315 天。将咪唑基离子液体作为添加剂与生物活性玻璃一起加入基于 HPTS 的荧光测定中，有望提高 HPTS 的光稳定性，并改善各种研究应用中荧光信号的可靠性和寿命。

期刊介绍： JPPA publishes the results of fundamental studies on all aspects of chemical phenomena induced by interactions between light and molecules/matter of all kinds. All systems capable of being described at the molecular or integrated multimolecular level are appropriate for the journal. This includes all molecular chemical species as well as biomolecular, supramolecular, polymer and other macromolecular systems, as well as solid state photochemistry. In addition, the journal publishes studies of semiconductor and other photoactive organic and inorganic materials, photocatalysis (organic, inorganic, supramolecular and superconductor). The scope includes condensed and gas phase photochemistry, as well as synchrotron radiation chemistry. A broad range of processes and techniques in photochemistry are covered such as light induced energy, electron and proton transfer; nonlinear photochemical behavior; mechanistic investigation of photochemical reactions and identification of the products of photochemical reactions; quantum yield determinations and measurements of rate constants for primary and secondary photochemical processes; steady-state and time-resolved emission, ultrafast spectroscopic methods, single molecule spectroscopy, time resolved X-ray diffraction, luminescence microscopy, and scattering spectroscopy applied to photochemistry. Papers in emerging and applied areas such as luminescent sensors, electroluminescence, solar energy conversion, atmospheric photochemistry, environmental remediation, and related photocatalytic chemistry are also welcome.
