Radiation detectors with noble gasses as the active medium are becoming increasingly integral to numerous experimental programs searching for physics beyond the standard model. Nearly all of these experiments rely to some degree on collecting scintillation light from noble gasses. The VUV wavelengths associated with noble gas scintillation mean that most of these experiments use a fluorescent material to shift the direct scintillation light into the visible or near UV band. We present highlights of a broad ranging R&D program related to noble gas detectors for neutrino physics, double beta decay, and dark matter. This program covers numerous areas from precise measurements of the fluorescence behavior of wavelength shifting films, to the prototyping of large are VUV sensitive light guides for multi-kiloton detectors, to efforts to dope the bulk of large noble gas detectors with wavelength shifters.
