Efficient ultraviolet emission of ZnS nanospheres: Co doping enhancement

Room temperature ferromagnetism and optical property of Zn1−xCoxS nanorods

“…According to the energy diagram of the defects distributed in the ZnS nanostructures [23], the blue region peaks from 380 to 450 nm can be attributed to the transition from the conduction band edge of ZnS to the surface states S and S vacancy [24,25], 492 nm to Zn vacancy [23], 560 nm to sulfur species on the surface of the ZnS NWs [26]. As the Co 2+ doped ratio increased, the PL intensity is decreased and no Co-related peak can be observed, indicating that the Co 2+ ions only act as the quenching centers of fluorescence, which is in agreement with the literatures [27,28].

Structural, optical, magnetic and half-metallic studies of cobalt doped ZnS thin films deposited via chemical bath deposition

“…In 2012, a study was published regarding the deposition of hexagonal cobalt doped ZnS thin films via pulsed laser deposition, 2 and the growth of cobalt doped ZnS nanoparticles using the colloidal method including the investigation of optical and magnetic properties. [3][4][5][6][7] Other methods to deposit/synthesize doped ZnS films and nanocrystals include: the aqueous method, 6 chemical bath deposition, 7,8 refluxing technique, 9 precipitation method, 10,11 pulsed laser ablation, 12 solid state reaction method, 13 solvothermal technique 14 and hydrothermal method, 15,16 aerosol assisted chemical vapour deposition and colloidal thermolysis. [17][18][19][20][21][22][23][24] Among these, CBD is the simplest and most cost effective method to synthesize thin films and nanocrystals.…”

Studies on the Zn x Co 1−x S thin films: A facile synthesis process and characteristic properties

“…However, the studies on thin film form of this material are limited in number. The occasional thin film reports include the synthesis via spray pyrolysis [11], pulsed laser deposition [12] and chemical bath deposition [13,14]. Other methods used for the synthesis of Zn-Co-S films and nanocrystals include: aqueous method [15], refluxing technique [16], precipitation method [17] and hydrothermal approach [18,19].…”
