Abstract

In this study, we demonstrate the fabrication of oxygen sensors based on metal nanoparticle and polymer nanosheets hybrid nanoassemblies containing phosphorescent dyes by the Langmuir-Blodgett (LB) technique. Polymer nanosheets contaning Ru(dpphen)32+ and Pt tetraphenylporphyrin (PtTPP) were fabricated by the LB technique. Gold and silver nanoparticles were prepared by citrate reduction method. These metal nanoparticles were immobilized onto polymer nanosheets containing amino end group (p(DDA/DADOO)) through immersion into a metal nanoparticle aqueous solution. Emission intensity measurement proved that the luminescense from Ru(dpphen)3 2+ was quenched in the presence of gold nanoparticles, whereas the intensity was enhanced in the presence of silver nanoparticles. In the case of PtTPP, emission intensity was enhanced by gold and silver nanoparticles. The effect of gold and silver nanoparticles on emission from phosphorescent dyes in different oxygen concentration was investigated.
