Elucidating the mechanism of dual-fluorescence in carbon dots

Author(s): Macairan JR; de Medeiros TV; Gazzetto M; Yarur Villanueva F; Cannizzo A; Naccache R;

Carbon dots have garnered significant attention owing to their versatile and highly tunable optical properties; however, the origins and the underlying mechanism remains a subject of debate especially for dual fluorescent systems. Here, we have prepared carbon dots from glutathione and formamide precursors via a one-pot solvothermal synthesis. Steady stat ...

A historical perspective on porphyrin-based metal-organic frameworks and their applications

Author(s): Zhang X; Wasson MC; Shayan M; Berdichevsky EK; Ricardo-Noordberg J; Singh Z; Papazyan EK; Castro AJ; Marino P; Ajoyan Z; Chen Z; Islamoglu T; Howarth AJ; Liu Y; Majewski MB; Katz MJ; Mondloch JE; Farha OK;

Porphyrins are important molecules widely found in nature in the form of enzyme active sites and visible light absorption units. Recent interest in using these functional molecules as building blocks for the construction of metal-organic frameworks (MOFs) have rapidly increased due to the ease in ...

Thermal properties of lipid bilayers derived from the transient heating regime of upconverting nanoparticles

Author(s): Bastos ARN; Brites CDS; Rojas-Gutierrez PA; Ferreira RAS; Longo RL; DeWolf C; Capobianco JA; Carlos LD;

Heat transfer and thermal properties at the nanoscale can be challenging to obtain experimentally. These are potentially relevant for understanding thermoregulation in cells. Experimental data from the transient heating regime in conjunction with a model based on the energy conservation enable th ...

On a local (de-)trapping model for highly doped Pr3+ radioluminescent and persistent luminescent nanoparticles

Author(s): Mandl GA; Van der Heggen D; Cooper DR; Joos JJ; Seuntjens J; Smet PF; Capobianco JA;

Trivalent praseodymium exhibits a wide range of luminescent phenomena when doped into a variety of different materials. Herein, radioluminescent NaLuF4:20%Pr3+ nanoparticles are studied. Four different samples of this composition were prepared ranging from 400-70 nm in size. Kinetic studies of radioluminescence as a function of X-ray irradiation time reve ...

The Key Role of Intrinsic Lifetime Dynamics from Upconverting Nanosystems in Multiemission Particle Velocimetry

Author(s): Tessitore G; Maurizio SL; Sabri T; Skinner CD; Capobianco JA;

Evaluation of particle dynamics at the nano- and microscale poses a challenge to the development of novel velocimetry techniques. Established optical methods implement external or internal calibrations of the emission profiles by varying the particle velocity and are limited to specific experimental conditions. The proposed multiemission particle velocime ...

Molecular Copper(I)-Copper(II) Photosensitizer-Catalyst Photoelectrode for Water Oxidation.

Author(s): Singh Z, Donnarumma PR, Majewski MB

Copper(II)-based electrocatalysts for water oxidation in aqueous solution have been studied previously, but photodriving these systems still remains a challenge. In this work, a bis(diimine)copper(I)-based donor-chromophore-acceptor system is synthesized and applied as the light-harvesting component of a photoanode. This molecular assembly was integrated ...
