Paper Abstract

The study of FT-IR spectrum, Raman spectrum, UV-Vis absorption spectrum as well as photoluminescence spectrum on organic ultraviolet semiconductor KIP-OUVS-1 has been investigated. The main vibrational peaks of organic ultraviolet semiconductor KIP-OUVS-1 in FT-IR spectrum and Raman spectrum have been assigned. The study of UV-Vis solution absorption spectrum on the organic ultraviolet semiconductor KIP-OUVS-1 shows that there is an obvious ultraviolet absorption peak in 210~280nm range, there are several ultraviolet absorption peaks in 290~390nm range too. The photoluminescence spectra of organic ultraviolet semiconductor KIP-OUVS-1 at different excitation wavelengths have also been investigated, the result shows that in the excitation wavelength of 220~360nm range, the shapes for different photoluminescence peaks are similar under different excitation wavelengths, the sole difference among them is strength of the peaks. At 280nm and 300nm excitation wavelengths, the relatively strong peaks have been gotten, at 220nm and 250nm excitation wavelengths, however, the photoluminescence peaks are relatively weak. Furthermore, for organic ultraviolet semiconductor KIP-OUVS-1, the photoluminescence peaks have a stokes' red shift compared with those absorption peaks for the solution samples, and an enantiomorphous symmetry, which is the powerful experimental proof of Franck-Condon theory, between the absorption spectrum and photoluminescence spectrum has been observed too. For the reason that the organic ultraviolet semiconductor KIP-OUVS-1 may be used to prepare large-area thin film and flexible device on low-price, flexible substrates by means of thermal evaporation and solution method, thus, the authors deduce that the organic ultraviolet semiconductor KIP-OUVS-1 may have an important application potential in ultraviolet optoelectronic detecting or lighting field.
