Performance and materials aspects of Ge:Be photoconductors [PDF]
Ge:Be photoconductors were developed for low photon background applications in the 30 to 50 MM wavelength region. These detectors provide higher responsivity and lower noise equivalent power (NEP) than the Ge:Ga detectors currently operating in this ...

High-quality 100% Ce3+:(Lu1−xYx)2SiO5 single crystals grown by the hydrothermal technique
The growth of Ce:(Lu _1−x Y _x ) _2 SiO _5 single crystals by the hydrothermal technique is demonstrated. Crystallographic defects are suppressed thanks to the growth at much lower temperatures, and therefore, the complete incorporation of cerium in the ...

Optical and structural properties of aluminium oxide thin films prepared by a non-aqueous sol-gel technique [PDF]
Clear aluminium oxide sols without precipitation were synthesized via a non-aqueous sol-gel technique using three different alcohols (ethanol, isopropanol and n-butyl alcohol) as solvent, aluminium sec-butoxide as a precursor and acetyl acetone as a ...

Phonon anomalies in optical spectra of LiNbO3 single crystals [PDF]
LiNbO3 single crystals were grown by the Czochralski technique in an air atmosphere. The critical crystal diameter Dc = 1.5 cm and the critical rate of rotation wc = 35 rpm were calculated by equations from the hydrodynamics of the melt.
