Study on Ultraviolet Spectrum Property of Ultraviolet Filter
The dye 2,7-dimethyl-3,6-diazacyclohepta-1,6-diene perchlorate was prepared by condensation reaction and characterized by elemental analysis, infrared spectroscopy and UV-visible techniques. The influences of dye solution and dye-doped polyvinyl alcohol (PVA) film with different concentrations on the property of UV spectroscopy were mainly investigated. Optical transmission spectra indicate that maximum absorption peaks for dye solution and dye-doped PVA film feature at 322 nm and 325 nm, respectively. With increasing dopant concentration, dye solution and dye-doped film exhibit strong absorption at cut-off region (285~345 nm) and are high transmissive at solar blind spectral region (240~285 nm). The sample composed of dye solution or dye-doped film, inorganic crystal and coloured glass as solar blind filter was demonstrated.
