Absorptivity measurements for the 3.39 μm He-Ne laser line are reported for acetylene, ethylene, and propylene over the temperature ranges 1500 to 3000 K (acetylene), 1000 to 2000 K (ethylene), and 700 to 2300 K (propylene). In contrast to the behavior of other hydrocarbons, the absorptivities of acetylene and ethylene increase with increasing temperature. The conventional spectroscopic analysis of line positions based upon high-resolution infrared spectroscopy at room temperature and approximate line-broadening theory indicate that no absorption at all would be expected for acetylene or ethylene. The time-resolved absorption profiles and computer models of the chemical behavior expected for shock-heated test gas confirm that the absorption is really due to these molecules, but must be attributed to some heretofore unidentified absorption process.

The Eu

The effect of hydrostatic pressure (varying up to 110 kbar) at the room temperature on three lines at 594nm, 615nm and 619nm positions in emission spectra and fluorescence lifetime t of the Eu3+ for 0-2 line (5D0→7F2 transition) in LuVO4: Eu3+ nanoparticles was studied. The results showed that the increase of the pressure induced lines red shift towards longer wavelengths for all considered lines with different rate. Also, the fluorescence lifetime τ for 5D0 → 7F2 transition nonlinearly decreased with pressure in the considered pressure range. Line positions and fluorescence lifetime τ, were explained by a model which took into account the effect of high pressure on: refractive index of crystal; compression, polarizability of the crystal and individual ions. Satisfactory agreement between measured and theoretical predicted values with error less than 2% was obtained.
