Silver Nanocomposite

A nanocomposite of indigo carmine doped polypyrrole/silver nanoparticles was obtained by a one-step electrochemical process. The nanocomposite was characterized by scanning electron microscopy, infrared spectroscopy, ultraviolet-visible-near infrared spectroscopy, and cyclic voltammetry. The simple one-step process allowed the growth of silver nanoparticles during the polymerization of polypyrrole, resulting in films with electrochromic behavior and improved electroactivity. In addition, polypyrrole chains in the nanocomposite were found to present longer conjugation length than pristine polypyrrole films.

Fluorescence Characteristics

Rare earth is a general term for 17 chemical elements with atomic numbers of 21, 39 and 57~71 in group IIIB in the periodic table. Lanthanide complexes can show unique linear emission bands and have very long luminous lifetime. Lanthanide complexes can be used in electroluminous (EL) devices, lasers and light-emitting biosensors in visible and near-infrared spectra. Therefore, it is of great significance to find new lanthanide luminous complexes. The emission peak of rare earth europium complex is mainly located in the characteristic emission wavelength of 5D0→7F2 of Eu3+. The emission wavelength is about 613nm, and it shows the fluorescence characteristics of europium ions. In order to further study the subject, this paper will focus on the current research on luminous rare earth complexes-organic complexes centered on Eu3+(emission red light). This paper summarizes the luminous principle of rare earth europium and its application in some fields, and expounds the existing problems at present and looks forward to its application prospect in the future.
