Abstract
Size and morphology controlled silver sulfide (Ag2S) nanoparticles were synthesized using single (oleylamine) and mixed (octadecene and dodecanethiol) solvents by thermal decomposition method. Structural and morphological properties of Ag2S nanostructures were analyzed by X-ray diffraction method and transmission electron microscope. Comparatively higher crystalline Ag2S nanoparticles were synthesized in single solvent than mixed solvent, however, larger size of the particles (>10 nm) synthesized in single solvent became fluorescence inactive. The controlled size of 3-5 nm in diameter was achieved irrespective of increasing temperature till 225 °C by mixed solvent synthesis and the photoluminescence showed the emission in the second near infrared region (NIR II).
