AbstractWe describe new results observed during resonant excitation in the excitonic region of GaAs grown directly on Si by organometallic vapor phase epitaxy. Two resolved features were found in the light hole photoluminescence (PL) region, one identified with a free exciton process and the other with donor-related transitions. Features which track the laser excitation line were observed and identified with a process in which a donor is excited from the n=l ground state to an n=2 excited state. The PL excitation spectra associated with these features have spectral widths as narrow as 1.5 meV. PL spectral widths of ~3 meV have been attained for the heavy hole exciton band, representing the narrowest value obtained for OMVPE material and an improvement of about 30% over our best previous results.

Existing Data

The A 1(3Π) state of IBr is observed in a free-jet expansion of IBr in Ar, following photolysis with ArF laser irradiation. Laser excitation spectra are obtained for the β 1(3P2) ← A transition in medium (0.5 cm−1) and high (0.08 cm−1) resolution. Sixteen ν′–ν″ bands recorded in high resolution are rotationally analyzed, providing the first detailed characterization of the lowest three νlevels in the A state. An additional ~50 bandheads in the ν″ = 0 and 1 progressions are recorded for both I79Br and I81Br. The new data, which sample ν′ levels in the range 31–71, are combined with existing information for low ν in the β state to provide improved constants for the β state. These results are merged with least-squares parameters from a detailed reanalysis of existing data for the A and X(1Σ+) states to yield spectroscopic parameters valid for ν = 0–20 in the X state and ν = 0–26 in the A state. Among these results are the first precise estimates of the equilibrium parameters in the A state: Te = 12 369.68 (14) cm−1, ωe = 134.22 (13) cm−1, Be = 0.042 40 (5) cm−1, Re = 2.8583 (16) Å.

A variety of fluorescence spectra have been measured interferometrically, demonstrating the feasibility of Fourier Transform Fluorescence Spectrometry (FT-FS). Emission spectra have been measured with the use of a monochromatic source and an interferometer as the emission selector. Excitation spectra have been measured with the use of a multi-line laser. Fluorescence polarization spectra have also been recorded with the use of laser excitation. The analytical characteristics of working curves are discussed.

Laser-excitation spectra of the rotational structure of the A6Σ+ – X6Σ+ transition of MnS has been performed. The combination of a single-mode dye laser and a high-resolution spectrometer have allowed analysis of a very congested spectrum in which the spin–rotation interaction completely dominates the spin–spin interaction. The (0,1) and (0,3) bands have been analyzed from laser-excitation spectra, and some information has been extracted from the emission spectrum of the (0,0) band. In addition, observation of a second band system confirms results already published by Monjazeb and Mohan.

The delayed luminescence of Mo atoms was observed in XeCl laser excitation of Mo(CO)6 gas. The observed luminescence was explained by production of Mo Rydberg atoms under UV laser excitation of Mo(CO)6.
