Measurements are reported on the refractive index n and of the static electro-optic coefficient r41 as a function of wavelength throughout the visible for Bi4Ge3O12 and Bi4Si3O12. Both materials exhibit large dispersion. At 633 nm, n=2.0975 for the germanate and 2.0211 for the silicate. The corresponding values for r41 are 0.95×10−10 cm/V and 0.54×10−10 cm/V, respectively.
Stimulated emission is reported for two polymethine dyes dissolved in glycerol when pumped by a Q-switched ruby laser. The materials are 1, 1'-diethyl-2,2'-dicarbocyanine iodide, and 1, 1'-diethyl-4, 4'-carbocyanine iodide. The emission wavelength is variable over the range 750 nm to 790 nm, depending on cell length. Oscillation has been observed on both the 0–0 and 0–1 vibrational transitions.
Carbon-doped platelets of GaP have been grown from gallium solution using a propane doping source. Acceptor concentrations of up to about 4×1017 cm−3 were obtained. The ionization energy was found to be 41±3 meV and 79 K mobilities up to 1786 cm2/V sec were observed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
