Abstract :
We demonstrate robust excitonic gain from colloidal close-packed, CdSe-based nanocrystal quantum dot thin films at record low threshold excitation energy of 90 μJ/cm2 for amplified spontaneous emission. The optical gain is employed in pulsed optically pumped quantum dot vertical cavity surface emitting lasers in the green and the red, respectively.
