Optical Field Induced Upconversion in Quantum Dots from Mid- and Long-Wavelength Infrared Radiation

We investigate the interaction of the optical electric field of intense sub-picosecond infrared pulses, between 3.5 and 12 micrometers, with visible quantum dots materials. Significant visible luminescence is observed from upconversion of the infrared light.
