PbS Colloidal Quantum Dot Photodetectors operating in the near infrared
Colloidal quantum dots have recently attracted lot of interest in the fabrication of optoelectronic devices due to their unique optical properties and their simple and low cost fabrication. PbS nanocrystals emerged as the most advanced colloidal material for near infrared photodetectors. In this work we report on the fabrication and characterization of PbS colloidal quantum dot photoconductors....
متن کاملNear-infrared-induced electron transfer of an uranyl macrocyclic complex without energy transfer to dioxygen.
Photoexcitation of dichloromethane solutions of an uranyl macrocyclic complex with cyclo[1]furan[1]pyridine[4]-pyrrole () at the near-infrared (NIR) band (1177 nm) in the presence of electron donors and acceptors resulted in NIR-induced electron transfer without producing singlet oxygen via energy transfer.

متن کاملPressure tuning of an ionic insulator into a heavy electron metal: an infrared study of YbS.
Optical conductivity [sigma(omega)] of YbS has been measured under pressure up to 20 GPa. Below 8 GPa, sigma(omega) is low since YbS is an insulator with an energy gap between a fully occupied 4f state and an unoccupied conduction (c) band. Above 8 GPa, however, sigma(omega) increases dramatically, developing a Drude component due to heavy carriers and characteristic infrared peaks. It is shown...
متن کاملD ? f energy transfer in heteronuclear Ir(III)/Ln(III) near-infrared luminescent complexes
A series of d/f dinuclear complexes Ir Ln [where Ln = Eu(III), Gd(III), Yb(III) and Nd(III)] are reported. The core structure consists of a rigid skeleton containing two different types of receptor site in a single molec-ular motif designed to combine a transition metal ion [Ir(III)] and a lanthanide ion [Ln(III)] in different binding sites at either end of fully conjugated bridge to facilitate...
