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.
