Abstract

The incorporation of a prototypical rosamine fluorescent dye from organic solutions into transparent and microstructured columnar TiO2 and SiO2 (MO2) thin films, prepared by evaporation at glancing angles (GAPVD), was evaluated. The aggregation of the adsorbed molecules, the infiltration efficiency and the adsorption kinetics were studied by means of UV-Vis absorption and fluorescence spectroscopies. Specifically, the infiltration equilibrium as well as the kinetic of adsorption of the emitting dye has been described by a Langmuir type adsorption isotherm and a pseudosecond order kinetic model, respectively. The anchoring mechanism of the rosamine to the MO2 matrix has been revealed by specular reflectance Fourier transform infrared spectroscopy and infiltration from aqueous solutions at different pH values. Finally, the sensing performance towards NO2 gas of optimized films has been assessed by following the changes of its fluorescence intensity revealing that the so-selected device exhibited improved sensing response compared to similar hybrid films reported in the literature.

摘要

评估了通过掠角蒸发法（GAPVD）制备的透明微结构柱状TiO₂和SiO₂（MO₂）薄膜从有机溶液中掺入典型的玫瑰胺荧光染料的情况。通过紫外可见吸收光谱和荧光光谱研究了吸附分子的聚集、渗透效率和吸附动力学。具体而言，发射染料的渗透平衡和吸附动力学分别用朗缪尔型吸附等温线和伪二级动力学模型进行了描述。通过镜面反射傅里叶变换红外光谱和在不同pH值的水溶液中的渗透，揭示了玫瑰胺与MO₂基质的锚定机制。最后，通过跟踪其荧光强度的变化评估了优化薄膜对NO₂气体的传感性能，结果表明，与文献报道的类似混合薄膜相比，如此选择的器件表现出了更好的传感响应。
