Wet-chemically synthesized CdSe seeded CdS nanotetrapods incorporated into silica matrices have been explored as high performance nanocrystal-based optical amplifiers. Varying the physical dimensions of the tetrapods allowed for room temperature biexcitonic amplified spontaneous emission (ASE) at wa...
