Large-scale synthesis of single-crystalline MgO with bone-like nanostructures

Magnesium oxide nanocrystals via thermal decomposition of magnesium oxalate

“…On pure MgO, the optical excitation of 5-fold coordinated O 2 À anions in (1 0 0) planes lies at 185 nm (6.6 eV), i.e., below the wavelength accessible in nonevacuated spectrometers (l 4200 nm). Although MgO is a typical wide bandgap insulator, the PL properties of its nanocrystals have been studied because of the presence of defects [14,41]. The PL spectrum of the MgO nanocrystals is shown in Fig.…”

“…Many different synthetic routes provide nanoscale MgO including sol-gel [12], hydrothermal/solvothermal [13,14], laser vaporization [15], chemical gas phase deposition [16], aqueous wet chemical [17], surfactant methods [18], polyol-mediated thermolysis process [19], and microwave-assisted method [20].…”

Comparative study of microwave and conventional methods for the preparation and optical properties of novel MgO-micro and nano-structures

“…However, the useful properties of MgO are further enhanced when used as nano-size powder with novel nano structures. Many different synthetic routes provide nanoscale MgO including sol-gel [8], hydrothermal/solvothermal [9,10], laser vaporization [11], chemical gas phase deposition [12], aqueous wet chemical method [13], surfactant methods [14], polyol-mediated thermolysis process [15]. In the above mentioned methods, limitations such as requirement of sophisticated equipments, many processing steps, more time, template, surfactant, and energy dissipation in the preparation of MgO nanostructures were observed.…”

Investigation of the optical properties of Mg(OH)2 and MgO nanostructures obtained by microwave-assisted methods

“…A number of researchers have used magnesium as the starting material for the preparation of magnesium oxide and magnesium hydroxide using different methods [22][23][24][25][26][27]. In ref.…”
