Description

High resolution ultraviolet-to-visible image conversion using photo-luminescence emitted by self-assembled CdSe/ZnCdMgSe quantum dots was investigated. The visible images centred at 585 nm with a resolution of 2 μm and 5 μm were obtained using a cw-He-Cd laser at the 325 nm excitation wavelength and with 150 fs laser pulses tuned to the second harmonic generation at 400 nm, respectively. The resolution limitations of visible images are discussed, and a high resolution optical system for the ultraviolet-to-visible image conversion is proposed
