Abstract

Hybrid hydrogels based on poly(N-isopropylacrylamide) and poly(acrylamide) containing CdTe quantum dots with UV sensitive response and including NaYF₄:Yb/Er nanoparticles have been prepared through glow discharge electrolysis plasma. The fluorescence characteristic and temperature sensitivity of the prepared hydrogels have been most extensively studied. In addition, scanning electron microscopy, X-ray diffraction, differential scanning calorimetry were determined to characterize the morphology, degree of crystallinity and the phase transformations of the hydrogels. The results suggested that the phase transition temperature of the hydrogels was 32.5°C and the hydrogels had good up-conversion and down-conversion fluorescence properties. Moreover, hybrid hydrogels had a reversible temperature response performance.

荧光/温度多敏杂化水凝胶的简便合成

摘要

基于聚（N-异丙基丙烯酰胺）和聚（丙烯酰胺）的杂化水凝胶，其中包含具有对UV敏感的响应的CdTe量子点，并且包含NaYF ₄通过辉光放电电解等离子体制备了：Yb / Er纳米粒子。已对制备的水凝胶的荧光特性和温度敏感性进行了最广泛的研究。此外，测定了扫描电子显微镜，X射线衍射，差示扫描量热法以表征水凝胶的形态，结晶度和相变。结果表明，水凝胶的相变温度为32.5℃，具有良好的上转换和下转换荧光性能。此外，杂化水凝胶具有可逆的温度响应性能。
