A semiconductor microsphere laser based on colloidal nanoplatelets is demonstrated comprising a micron-sized supraparticle obtained by self-assembly of core/shell CdSe/ CdS nanoplatelets with peak luminescence at 660nm. It shows multimode laser emission between 665 and 695nm with threshold at 200 nJ (28 ± 17 mJ.cm -2 ).
