摘要

聚合物发光薄膜的开发研究往往忽略了沉积方法因素的变化对薄膜性能的影响，特别是对其光谱性能的影响。本研究旨在探讨浓度、掺杂配合物、沉积方式、滴铸和自旋镀膜对掺铕（III）配合物[Eu(tta)3(H2O)2]和[Eu(tta)3(amx)]的PMMA基体发光膜性能的影响，以及这些变量对其光谱性能的影响。使用了红外光谱、氢核磁共振光谱、热重法、紫外可见电子吸收光谱、激发和发射光谱、扫描电子显微镜和原子力显微镜等技术，重点研究了光谱表征。结果表明，所制备的薄膜在光致发光标记、紫外辐射监测、光电器件和其他发光材料体系中具有重要的应用潜力。

Effect of the deposition method on the luminescent properties of PMMA films doped with Eu3+ complexes containing amoxicillin drug ligand

The research on the development of luminescent polymer films often overlooks the impact of variations in deposition method factors on the properties of the films, particularly their spectral properties. This study aims to investigate the effects of concentration, dopant complex, and deposition methods drop casting and spin coating on the properties of luminescent films in PMMA matrix doped with europium (III) complexes, [Eu(tta)₃(H₂O)₂] and [Eu(tta)₃(amx)], and how these variables affect their spectral properties. Techniques such as infrared spectroscopy, hydrogen nuclear magnetic resonance spectroscopy, thermogravimetry, UV–Vis electronic absorption spectroscopy, excitation and emission spectroscopy, scanning electron microscopy, and atomic force microscopy were used, with a focus on spectral characterization. The results indicate that the produced films have significant potential for applications in photoluminescent labeling, UV radiation monitoring, optoelectronic devices, and other luminescent material systems.

期刊介绍： The purpose of the Journal of Luminescence is to provide a means of communication between scientists in different disciplines who share a common interest in the electronic excited states of molecular, ionic and covalent systems, whether crystalline, amorphous, or liquid. We invite original papers and reviews on such subjects as: exciton and polariton dynamics, dynamics of localized excited states, energy and charge transport in ordered and disordered systems, radiative and non-radiative recombination, relaxation processes, vibronic interactions in electronic excited states, photochemistry in condensed systems, excited state resonance, double resonance, spin dynamics, selective excitation spectroscopy, hole burning, coherent processes in excited states, (e.g. coherent optical transients, photon echoes, transient gratings), multiphoton processes, optical bistability, photochromism, and new techniques for the study of excited states. This list is not intended to be exhaustive. Papers in the traditional areas of optical spectroscopy (absorption, MCD, luminescence, Raman scattering) are welcome. Papers on applications (phosphors, scintillators, electro- and cathodo-luminescence, radiography, bioimaging, solar energy, energy conversion, etc.) are also welcome if they present results of scientific, rather than only technological interest. However, papers containing purely theoretical results, not related to phenomena in the excited states, as well as papers using luminescence spectroscopy to perform routine analytical chemistry or biochemistry procedures, are outside the scope of the journal. Some exceptions will be possible at the discretion of the editors.
