Effect of temperature on structural, optical and photoluminescence studies on ZnO nanoparticles synthesized by the standard co-precipitation method

Photosensitization of Fe3O4/ZnO by AgBr and Ag3PO4 to fabricate novel magnetically recoverable nanocomposites with significantly enhanced photocatalytic activity under visible-light irradiation

“…The UV emission is attributed to the recombination of free excitons and visible emissions are ascribed to the defects such as oxygen vacancies (V 0 ), oxygen intersites (O i ), surface dangling bonds, zinc interstitials (Zn i ), and zinc vacancies (V Zn ). In the present work, the broad peak centered at nearly 410 nm is related to transfer of electrons from the zinc interstitials to valence band (VB) of the samples[42]. The electrons excited to the conduction band (CB) of the samples may transfer to the zinc interstitial through a nonradiative transition.…”

“…The electrons excited to the conduction band (CB) of the samples may transfer to the zinc interstitial through a nonradiative transition. After that, these electrons transit to the VB of the samples by producing an emission peak nearly at 410 nm[42]. The significant quenching of the emission in the Fe 3 O 4 /ZnO/AgBr/Ag 3 PO 4 (20%) nanocomposite compared to the other photocatalysts…”

Biosynthesis of Silver Nanoparticles Using Natural Plant Extract and Its Catalytic Reductive Degradation of Acid Violet 7

“…Temperature was another important parameter for the reaction of AgNPs synthesis [22] . Temperature was known to affect nanoparticles synthesis in a variety of ways.…”

“…Silver plays an important role in drug delivery, wastewater treatment, agriculture, biosensor and textile industries [13][14][15] . The synthesis of nanoparticles by various physical and chemical methods, such as ultrasonic irradiation [16] , laser ablation [17] , evaporative cooling [18] , chemical vapor deposition [19] , explosion [20] , impregnation [21] , co-precipitation [22] , sol-gel [23] and deposition-precipitation [24] , has been reported extensively. However, there is still a need for a more economic, commercially and eco-friendly route to synthesize silver nanoparticles.…”

Sol-gel, hydrothermal, and combustion synthetic methods of zinc oxide nanoparticles and their modification with polyaniline for antimicrobial nanocomposites application

“…This includes the selection of reactants, their concentrations, and the reaction condition. For example; the calcination temperature has a great influence on the morphology and the size of the synthesized ZnO [6][7][8][9]. Matei et al [3] presented the most common techniques used for the synthesis of ZnO NPs such as; mechanochemical [10], precipitation [11][12][13], emulsion [14], sol-gel [15,16], microwave [17], hydrothermal [18], combustion [5,19], sonochemical synthesis [20].…”
