Organic-Inorganic Sol-Gel Composites Incorporating Semiconductor Nanocrystals for Optical Gain Applications

Organic-inorganic sol-gel composite incorporating highly emitting CdSe/ZnS quantum dots and CdSe/CdS/ZnS quantum rods is reported. Optical gain measurements conducted on a quantum rod/sol-gel composite film show stable room temperature amplified spontaneous emission under ambient conditions.
