Mn-doped ZnS phosphorescent quantum dots: Coumarins optical sensors
(Elsevier Science Sa, 2017-01)
Mn-doped ZnS quantum dots (QDs) have increasingly attracted much attention as luminescent sensors. Mn+2doping promotes a strong phosphorescence-like emission, allowing the development of novel and highly selective sensing ...
Influence of Ag+ and Mn2+ ions on structural, optical and photoluminescence features of ZnS quantum dots
(Corporación Universidad de la Costa, 2021)
Förster resonance energy transfer mediated enhancement of the fluorescence lifetime of organic fluorophores to the millisecond range by coupling to Mn-doped CdS/ZnS quantum dots
(IOP Publishing, 2015-12)
Manganese-doped CdS/ZnS quantum dots have been used as energy donors in a Förster-like resonance energy transfer (FRET) process to enhance the effective lifetime of organic fluorophores. It was possible to tune the effective ...
Síntesis y caracterización de nanopartículas de ZnS y ZnS dopado con Cu
El trabajo estudia las propiedades eléctricas y ópticas de nanopartículas de sulfuro de zinc (ZnS) puro y dopado con cobre con una concentración de 2%. La síntesis se realizó mediante el método simple de precipitación ...
Enhanced singlet oxygen production by photodynamic therapy and a novel method for its intracellular measurement
(Mary Ann Liebert, 2014-12)
The generation of singlet oxygen (SO) in the presence of specific photosensitizers (PSs) or semiconductor quantum dots (QDs) and its application in photodynamic therapy (PDT) is of great interest to develop cancer therapies ...
Generación de Quimiosensores del Nanocomposito Celulosa Bacteriana/Puntos Cuánticos como Indicador de Contaminación por Metales Pesados en Muestras Acuosas
(Universidad Santo TomásPregrado Química AmbientalFacultad de Química Ambiental, 2021-03-15)
In the last decade, contamination by heavy metals in aqueous media has become a global problem that has increased with the confluence of natural sources and, mainly, anthropogenic activities (industrial activities, mining ...
