Abstract

We discuss our design for a laser-scanning confocal microscope that will provide fluorescence images with diffraction-limited spatial resolution and spectral information. An achromatic design allows UV excitation while visible to 1000 nm emission is collected. A liquid nitrogen-cooled CCD spectrometer can record spectra over long periods of exposure. A liquid nitrogen vacuum cryostat allows the sample to be held in vacuum at fixed temperatures betwen 80 K and 325 K. We will employ this apparatus to investigate photoluminescence from individual semiconducting nanostructures, local environments in polymeric and biological materials, and interfaces of heterogeneous polymer blends.
