The second-​harmonic generation in chalcogenide glass-​ceramic doped with CdS nanocrystals

Résumé

An innovative way is proposed here to synthesize chalcogenide glass-​CdS nanocrystal composites by hot-​pressing a combination of Ge20Sb12S68 glassy powder and nonlinear CdS nanoparticles. The cadmium sulfide nanoparticles, which possess the second-​harmonic generation property, were synthesized from basic cadmium soln. strongly complexed by amine. The obtained nanocomposites present a homogeneous distribution of the crystals. The transmission reaches 30​% at 5 μm and up to 60​% at 10.6 μm. The second-​harmonic generation at 0.9 μm has been detected. This technique can overcome the uncontrollable hetero-​crystn. which tends to occur in the glass-​ceramics prepd. by the conventional thermal treatment method.
