title: [Preparation by spin-coating technology and characterization of UV-enhanced Lumogen film].
abstract: As an effective way to increase the UV response for CCD/CMOS, the advantage of the Lumogen film is the simple process and low cost. In the present paper the Lumogen film was deposited onto fused silica slides by the spin-coating way, which has less damage than PVD physical vacuum deposition) way. The main test and analysis of the thin-film include transmission spectrum, absorption spectrum, and excitation and emission spectrum. It was showed that these coatings were transmitted well in visible region (lambda > 400 nm), and emitted a yellowish green glow centered at -525 nm together with a wide excitation spectrum range from 200 to 400 nm. The synthesis shows that Lumogen coatings match accurately with the detected spectrum of conventional silicon-based image sensors, which makes this kind of thin films an ultraviolet responsive coating for sensors.
