RED, GREEN, AND BLUE LASING ENABLED BY SINGLE-EXCITON GAIN COLLOIDAL QUANTUM DOT FILMS

摘要

The methods and materials described herein contemplate the use films of colloidal quantum dots as a gain medium in a vertical-cavity surface-emitting laser. The present disclosure demonstrates a laser with single-exciton gain in the red, green, and blue wavelengths. Leveraging this nanocomposite gain, the results realize a significant step toward full-color single-material lasers.
