A key enabling technology for many liquid noble gas (LNG) detectors is theuse of the common wavelength shifting medium tetraphenyl butadiene (TPB). TPBthin films are used to shift ultraviolet scintillation light into the visiblespectrum for detection and event reconstruction. Understanding the wavelengthshifting efficiency and optical properties of these films are critical aspectsin detector performance and modeling and hence in the ultimate physicssensitivity of such experiments. This article presents the first measurementsof the room-temperature microphysical quantum efficiency for vacuum-depositedTPB thin films - a result that is independent of the optics of the TPB orsubstrate. Also presented are measurements of the absorption length in thevacuum ultraviolet regime, the secondary re-emission efficiency, and moreprecise results for the "black-box" efficiency across a broader spectrum ofwavelengths than previous results. The low-wavelength sensitivity, inparticular, would allow construction of LNG scintillator detectors with lighterelements (Ne, He) to target light mass WIMPs.
