30 years of colloidal quantum dots

From may 26 to 28 2014, the group is organizing a conference for the 30th anniversary of colloidal quantum dots.



The core/shell CdSe/CdS quantum dot imaged on this picture has a diameter of 12nm. It has been taken with a Transmission Electron Microscope at magnification 400,000x.  Due to a favorable orientation of the crystal axes, one can distinguish the electron-opaque atoms.

Welcome at the Quantum Dot group from ESPCI – LPEM

The ESPCI - LPEM Quantum Dots Group is specialized in chemical synthesis and optical characterization of colloidal quantum dots.We have open positions for:
PhD students
Stages de Master - Master Internships

New infrared quantum dots

Our group reports the synthesis of HgSe quantum dots with the reddest infrared properties ever reported, with peak absorption up to 20µm. once coupled with As2S3 as ligand the film of these nanocrystals present large mobility close to 100cm2V-1s-1, which is very promissing fro their integration into photodetectors. For more details : Infrared photo-detection based […]

Group meeting on June 23, 2014

Lundi prochain, le 23 juin à 12h, Tim Harris nous parlera de ses recherches à Janelia Farm. Tim est un ancien de Bell Labs qui connait bien les QDs (il est co-auteur du papier de Nirmal en 1996 sur le blinking). Il est actuellement directeur du département de physique appliquée et d’instrumentation à Janelia Farm […]
