Red emission from Eu³⁺: PVA polymer film

Abstract

Bright red luminescent Eu 3þ doped polyvinyl alcohol (PVA) films were made by solution casting technique. The emission performance of these films was studied from the measurement of excitation, emission, and lifetimes. On irradiation with an UV source, the doped films emitted bright red light. Such luminescent polymer films are expected to find potential applications as new optical materials. Emission process in the system was explained by an energy level scheme.

Photoluminescence analysis of Sm3+ and DY3+ doped PVA films

“…Thus, it is interesting to study the luminescence properties of Sm 3+ and Dy 3+ : Poly vinyl alcohol (PVA) films. In our earlier articles, bright red and green colors emitting Eu 3+ and Tb 3+ ions doped PVA films were reported 24, 25. In the present article, emission analysis of Sm 3+ and Dy 3+ doped PVA films has been reported.…”

“…X‐ray diffraction spectrum and absorption spectrum of pure PVA film were reported in our earlier articles 24, 25. Figure 1 reports FTIR spectra of both RE 3+ doped and undoped PVA films.…”

Properties of poly(vinyl alcohol)–borax gel doped with neodymium and praseodymium

“…Some studies have also been reported on poly(vinyl alcohol) thin films doped with a single rare-earth viz. Ho 3+ , Er 3+ , Sm 3+ , Eu 3+ and Ce 3+ (Kumar et al 1997;Seeta Rama Raju et al 2006;Abdel-Kader and Anwer 2007;Abdelaziz 2011). We have not come across studies on PVA matrices with combinations of different rare-earth dopant species.…”
