Excited states of ozone are investigated based on the absorption spectrum measured in the wavelength region 105-200 nm. Two Rydberg series corresponding to the transition 6a1 → ns, np and 4b2 → ns and np were assigned for the most of the strong peaks in the absorption spectrum. In 112-105 nm wavelengths, the progression of vibrational bands with an energy spacing of about 622 cm −1 was measured which was unknown before.Surf. Rev. Lett. 2002.09:125-128.

The polarization-dependent optical properties of InGaN/GaN multiquantum wells blue light-emitting diode with one-dimensional (1-D) plasmonic nanoparticles grating are investigated using an angle-resolved photoluminescence spectrometer. The light extraction efficiencies of the 1-D GaN grating coated with an Au layer and 1-D GaN grating coated with an Au nanoparticle monolayer are measured. It is shown that the light extraction efficiency of plasmonic nanoparticle grating coated with an Au nanoparticle monolayer is 1.4-fold higher than that of a 1-D GaN grating coated with Au film because the surface plasmon losses are conquered. In addition, the experimental dispersion of the surface plasmon (SP)-assisted light enhancement shows a good agreement with the dispersion of SP at the Au/GaN interface.
