title = "Plasmonic-ceria nanoparticles for automated optical fluorescence-quenching of dissolved oxygen",
abstract = "Due to its optical and structural characteristics, cerium oxide (ceria) nanoparticles have been used in wide variety of applications. This paper introduces the enhancement of visible fluorescence emission of ceria nanoparticlesthrough adding plasmonicgold nanoparticles (Au NPs) under violet excitation. Au NPs lead to enhance the formation of tri-valent ionization states of cerium ions with corresponding oxygen vacancies formation. In addition, the coupling between plasmonic waves of gold and emission spectrum of ceria offers another contribution to the enhancement of fluorescence intensity.Then, gold-ceria nanoparticles have been applied as optical sensing material for dissolved oxygen in aqueous media based on fluorescence quenching mechanism.The sensed data is automatically collected and processed through a wireless sensor network-based communication infrastructure with smartdata and feedback management capability.",
