This investigation reports on the spectroscopic properties of trivalent Pr in YPO4. In particular, we show how the luminescence from the 1D2 level depends on the polarization of the emission and on the temperature of the sample. We also report on the decay kinetics of the 1D2 level, which show the lifetime decreasing as temperature is increased. Our observed lifetime of 440 µs is at low temperature and is significantly longer than that reported by other workers. We explain the temperature dependence of the 1D2 emission by considering the population redistribution in the 1D2 level, without invoking the existence of multiphonon relaxation. Finally, we estimate the radiative decay rates of individual crystal field levels within the 1D2 manifold.

The course of the conversion of methanol with water vapour was followed on a low-temperature Cu-Zn-Cr-Al catalyst at pressures of 0.2 and 0.6 MPa. The kinetic data were evaluated together with those obtained at 0.1 MPa and the following equation for the reaction kinetics at the given conditions was derived: r = [p(CH3OH)p(H2O)]0.5[p(H2)]-1.3.

Low Temperature Epitaxy

ABSTRACTComputer simulations of III-V molecular beam epitaxy (MBE) show that surface reconstruction induced modulation of kinetic rates could give rise to ordering in alloys. Results are also presented for the possible influence of an external ion beam in achieving low temperature epitaxy as well as smoother growth front under usual conditions.
