The correlation between the Peak of spontaneous spectra and the maximum of the injected carrier distribution in the energy band, the condition of the carrier distribution-maximum situated in the bandtail; the dependence of the carrier-distribution-maximum shifting-rate with injection level on the shape of the bandtail, and on whether or not the quasi-equilibrium distribution has been reached, have been analysed theoretically both under steady and transient cases.A new method for quantitatively determining the density-of-states distribution of the tail from the steady and transient emission spectra peak shifting is proposed. An important conclusion is that quansi-Fermi level do not exist during transient spontaneous emissions from GaAs doped with amphoteric silicon. Steady and transient time-resolved spectra from GaAs homojunction and heterojunc-tion samples doped with various dopants of different concentrations and different degrees of compensation, under various injection levels at 300 and 77K, are systematically measured. The experimental results agree well with the theoretical predictions, and on this qasis, the effect of bandtailing on the transient response time of spontaneous emission Is discussed.

The determination of trace uranium in sulfuric acid by measuring the laser induced fluorescence of uranyl ions with a N2 laser and a boxcar integrator has been investigated. Both a wavellength dispersive technique and a time-resolved technique were used. The effects of the concentrations of sulfuric acid and sulfate radical on the intensity and lifetime of uranium fluorescence have been measured. At low concentration of sulfuric acid, the intensity of uranyl fluorescence increases rapidly with ah increase of sulfuric acid concentration, and, as the concentration of sulfuric acid is more than 6 M, a saturation value of the intensity is reached. The influence of the concentration of sulfuric acid on the lifetime of uranyl fluorescence has also been examined. The fluorescence lifetime is 12 us to 46 μs for a concentration of H2SO4 at 0.5 to 8.0 M.The effects of the interference of other ions in nature water on the determination of uranium have been measured. It has been shown that the detection limit is better than 0.03 ppb and the precision is±7% at 0.5 ppb level in 6M H2SO4 mediun. There are no interference from a 10,000-fold amount of Na+, K+, NH4+, Mg2+, Ca2+, A13+, NO3-, and PO43-, and a 1,000-fold amount of Fe3+ and Mn2+.Chloride ion interferes strongly, but for an amount of 100-fold of uranium does not cause significant error in the results.The laser induced fluorescence method can be used in the analysis of trace uranium for natural water, effluents, biological and environmental samples.

On the basis of ref. [1], the time-resolved absorption spectrum of vibrational excited states v3 in BCl3 molecules are observed and investigated in higher laser energy flux. The excitation of vibrational states and a variety of energy transfer processes in relaxation, as well as their dependence on the pumping laser energy, the pressure of BCl3 and other parameters are measured. The result shows that there exists an ensemble of nonthermal distribution in vibrational states and the rotational energy transfer plays an important role in generating this nonthermal distribution. The processes of development of the BCl3 vi-bratioal excited absorption spectrum are discussed by using a simplified dynamical collision model. A simple relation Prv-v = c/K'(Tv,T<0,q) for the redistribution of the vibrational states and the analytical expressions for the equivalent vibrational temperature and the average number of the absorbed photons are obtained. They are qualitatively in agreement with experimental results.
