Red, Yellow, Green, and Blue Amplified Spontaneous Emission

Red, Yellow, Green, and Blue Amplified Spontaneous Emission and Lasing Using Colloidal CdSe Nanoplatelets Researchers discuss recent work studying materials combining the electronic structure of quantum wells with the processability of quantum dots. They suggest that this class of semiconductor nanomaterials, colloidal quantum wells, could be a promising medium for solid state lasers.
