Nanoparticles of wide band gap compounds, when doped with rare earth or transition metal ions, are perspective candidates for efficient phosphors in a new generation of light sources for an overhead illumination, i.e., in compact fluorescence lamps and in semiconductor-based white light emitting diodes. Mechanisms of emission enhancement in doped nanoparticles are discussed based on the relevant experimental...
ZnS nanocrystals (NCs) capped with tetramethylammonium (TMAH) were synthesized from ZnCl 2 ·2H 2 O and thiourea using a wet chemical process. Further treatments of the nanocrystals such as aging, and annealing have been conducted to examine the stability of the grown samples. The X-ray diffraction spectra show that the crystal has a zinc blende structure with particle size of about...
