Excitation transfer mechanism along the visible to the Near-IR in rhodamine J-heteroaggregates.

چکیده
An enhanced fluorescent emission of the dye Rhodamine 800 in the Near-IR is observed in the presence of other xanthene dye molecules (RhX) when they are hosted in different matrices due to the formation of a new type of fluorescent J-heteroaggregates. This enhanced emission of the acceptor occurs despite the low spectral overlapping and the low quantum yield of Rh800.

Rhodamine 6G and 800 J-heteroaggregates with enhanced acceptor luminescence (HEAL) adsorbed in transparent SiO2 GLAD thin films.
An enhanced fluorescent emission in the near infrared is observed when the Rhodamine 800 (Rh800) and 6G (Rh6G) dyes are coadsorbed in porous SiO(2) optical thin films prepared by glancing angle deposition (GLAD). This unusual behavior is not observed in solution and it has been ascribed to the formation of a new type of J-heteroaggregates with enhanced acceptor luminescence (HEAL). This article...
متن کاملThe Study of Photocatalytic Degradation Mechanism under Visible Light Irradiation on BiOBr/Ag Nanocomposite
Due to the pollution of dyeing and textile industry wastewaters in different colors and the need to remove these pollutants from the wastewaters, it is necessary to study and develop effective and efficient technology solutions required. To remove dye from aqueous solutions, photodegradation is employed as an effectively simple way. Thus, the BiOBr photocatalyst was chemically made by synthesis...

Heat transfer coefficient in nucleate pool boiling near critical heat flux at least one orderhigher than the convectional heat transfer modes. In this paper, an experimental setup isdesigned and fabricated to investigate the mechanism of heat transfer from boiling surface tobulk liquid near critical heat flux. The images of pool boiling near the high heat flux regionreveals that the individual ...
متن کاملHigh temperature acidic oxidation of multiwalled Carbon nanotubes and synthesis of Graphene quantum dots
The acid oxidation of carbon nanotube generally results in opening the close ends of the nanotube and to make surface modifications. Herewith, Multiwall carbon nanotubes (MWCNTs) were oxidized in acids at high temperature experimental conditions which led to the formation of graphene quantum dots (GQDs). High resolution transmission electron microscope (HRTEM), energy dispersive X-ray spectro...
