Abstract—

This paper reports the development and characterization of new inexpensive and safe light–time–temperature indicators for products of the pharmaceutical and food industries. For this purpose, we have prepared and characterized stable sols of titanium dioxide nanoparticles modified with titanium(IV) peroxo complexes. Electronic absorption spectroscopy, dynamic light scattering, scanning probe microscopy, and experimental kinetic data demonstrate that, varying synthesis conditions and, hence, the stability of the Ti(IV) peroxo complexes, one can ensure that their bleaching is symbatic with the degradation of a particular labeled object after the expiry date, and/or in the case of the required temperature conditions being not fulfilled, and/or during storage in the light. The most important result of this study is that we have found correlations between modification conditions of titanium peroxide sols, their optical properties, the morphology of films produced from them, and their bleaching kinetics under illumination.

摘要-

本文报告了针对制药和食品工业产品的新型廉价且安全的光照时间温度指示器的开发和特性。为此，我们制备并表征了用过氧化钛（IV）配合物改性的二氧化钛纳米粒子的稳定溶胶。电子吸收光谱，动态光散射，扫描探针显微镜和实验动力学数据表明，合成条件的变化以及Ti（IV）过氧配合物的稳定性，可以确保它们的漂白与a的降解相伴生。有效期后，和/或在未满足要求的温度条件的情况下，和/或在光照条件下存放的物品，应特别注明。
