Controlling of ZnO nanostructures by solute concentration and its effect on growth, structural and optical properties

Search for Origin of Room Temperature Ferromagnetism Properties in Ni-Doped ZnO Nanostructure

“…in a wide-gap semiconductors provides a conceivable means of tuning of both optical properties as well as ferromagnetism properties of a single material [8][9][10][11] . It also demonstrates that by simple change in the shape and size of nanomaterial it is possible to tune the physical properties of nanostructure [12][13][14] . However, present and existing theories and results [5][6][7] cannot satisfactorily articulate the origin of the witnessed ferromagnetism.…”

Synthesis of Ni-doped ZnO nanostructures by low-temperature wet chemical method and their enhanced field emission properties

“…The morphology of ZnO nanostructure is not only dependent on the preparation technique but also other external conditions such as reaction temperature, pH value, reaction time, solution concentration, doping, etc 5,7 . The most plausible mechanism known for ZnO nano structure is either layer by layer along the axial direction or by screw dislocation, we already discuss both mechanisms in our previous reports 5,7,32 . ZnO exhibit several crystal planes with different polarity This assists to grow ZnO in a different direction as a result to form flakes like morphology.…”

“…It is due to its remarkable and multifunctional properties such as direct bandgap of 3.37eV, high exciton binding energy 60 meV 1,2 . ZnO also shows numerous morphology such as nano-combs 3,4 , nanotubes 5 , nano-springs 6 , nanorods 7 , nanorings 8 nanowires 9 and nanoflower 10 , due to its significant physical and chemical properties, it's a potential candidate for various applications, such as photo-electronics devices 11,12 , nano-sensors [13][14][15][16][17] , nano-generators 18 , electronics devices 19,20 , dye-sensitized solar cells 21 , spintronics 22,23 , metal-ions detection 24 , photocatalytic 25 , etc. The last few decades ZnO has shown one of the most promising materials for FE device.…”

Influence of ammonia concentration on the microstructure, electrical and raman properties of low temperature chemical bath deposited ZnO nanorods

“…Wet chemistry methods have received much attention since they involve the use of simple experimental apparatus, low processing temperature and are environmentally friendly [12][13][14]. In particular, chemical bath deposition (CBD) is popular because it is a simple experimental setup, economical and can be used to deposit nanostructures on large, flexible and non-flexible substrates [15][16][17].…”
