12 years ago. PbS and PbSe would have very strong resonance in the reddish orange to near IR bands. (580 to about 2000nm wavelengths) Also they would be reasonably air stable as well.❤

Be advised that the sulphur precursor they use is not HMDS, as noted. It is most likely Hexamethyldisilathiane. HMDS, used to prepare Si wafers for photoresist, does not contain any sulphur.

Hi, very good video

Hi there, in the introduction part, when Ashley is describing the ingredients, she says add 1.4g of Oleic Acid, then explains that is kept in the fridge for preservation and then says, we add 1.2g of that. Can you please add a note with the correct amount?? thanks!

Can you suggest a procedure for MoSe2 nanoparticles and if the synthesis is possible without a glovebox?? Thank you
