Investigation of neodymium rare earth element doping in spray-coated zinc oxide thin films

Optical and Structural Characteristics of Rare Earth-Doped ZnO Nanocrystals Prepared in Colloidal Solution

“…In some reports, transition metal dopants, such as silver, increased the photoresponse of ZnO [13], while cobalt and manganese doping decreased its photoactivity [14]. The doping of bulk and micro/nanocrystalline ZnO using rare earth (RE) elements is another promising approach for tuning the PL properties and improving photocatalytic activity [15][16][17][18]. However, in contrast to bulk material, the effects of RE doping on ZnO quantum-confined nanocrystals obtained under ambient mild conditions of "green" colloidal synthesis, e.g., the DMSO solvent is low-toxic and is accepted in pharmaceuticals [19], have not received proper attention.…”

Optimizing the structural and photocatalytic performance of Ag‐decorated ZnO/Zn(OH)2 nanoparticles for RhB degradation

“…This important fundamental difference allows for the separation of microstructural, small crystalline size, and a reflection enlarged by micro tension. Accordingly, the crystal dimensions can be calculated by the following equation 24 : $$$$\begin{equation*}\beta {\mathrm{cos}}\theta \ = \frac{{K\lambda }}{D}\ + 4\varepsilon {\mathrm{sin}}\theta \end{equation*}$$$$where β is the full width at the middle maximum at 2 θ , θ is the diffraction angle, K is a constant equal to 0.9, λ is the X‐ray wavelength (0.154 nm), D is the crystal size in nm, and ε is the lattice tension. Figure 3A,B shows the graphs of different aging time‐coated ZnO structures by the W–H method and Ag‐decorated ZnO structure, respectively.…”

Fabrication of plasmonic junction diodes based on Ag@ZnO core-shell nanostructures

“…Since ZnO is a highly permeable material with a wide conduction band gap of 3.4 eV at room temperature and a large binding energy of 60 meV, it is ideal for many device constructions with properties such as biocompatibility [3]. ZnO semiconductor is frequently used in many applications, mainly because of its good photoelectric and thermoelectric properties [4]. Applications such as thin film transistors, gas sensors, optoelectronic devices, photoelectric devices, UV detectors, solar cells, thermoelectric devices, biosensors, and pH sensors are the areas where they are frequently used [5].…”
