Synthesis and characterization of Cu2+ doped ZnS nanoparticles using TOPO and SHMP as capping agents

Investigation of structural, optical and morphological properties of copper doped zinc sulphide nanoparticles

“…This may be due to the fact that the Cu atom may be partially substituted into the Zn position in ZnS nanoparticles. The peak appearing around 509 cm À 1 may be due to the presence of sulfur-oxygen interaction [20]. It is further observed that the transmittance peaks of ZnS: Cu 2 þ are slightly shifted towards lower wave number when compared to undoped ZnS and this might be attributed due to the presence of the doping ions.…”

(NaPO3)6-assisted wet formation of dispersive Mg(OH)2 nanoplates

“…5b). The red-shift of P-O stretching vibration was connected with the electron withdrawing of hydroxyl on Mg(OH) 2 surface, 11 revealing the presence of Mg-O bond owing to the interaction of Mg on Mg(OH) 2 and O in SHMP. The adsorption of SHMP on Mg(OH) 2 surface prevented the agglomeration and promoted the formation of Mg(OH) 2 nano-plates with high crystallinities.…”

Nanobiosensors and Nanobioanalyses

“…This "electronic" passivation is absolutely crucial to maintaining emission effi ciency, because any un-terminated dangling bonds can result in the trapping of electrons at the surface of QD before they have a chance to emit photons (Kuppayee et al 2011 ). The inner black circle represents the core nanocrystal of the QD.…”
