Layer-by-layer chemical deposition technique for thin film assembly of deposited nano-sized magnesium(II)–5,7-dinitro-8-hydroxyquinolate: Characterization and spectral–optical–electrical properties

SILAR Deposition of Ni(bpy)3X: {X = (NCS)2, (Fe(CN)5NO), and (Ag(CN)2)2} Thin Films on Glass Substrates

“…All studied Ni(II)-complexes thin layers have a maximal absorbance observed between 238 nm-241 nm) corresponding a π-π* or n-π* electronic transition between the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) [14,17,[30][31][32]. The absorption coefficient and gap's energy has been the determined using the UV-Vis absorbance spectra of as-deposed thin layers synthesized in optimal conditions (120 cycles of dipping, 20° C and 10 -2 M ); the information about direct transitions was determined from the analysis of the spectral dependence of the absorption near the fundamental absorption edges within the framework of one electron [15,17]. The equation that relates the absorption coefficient α and the energy gap are given as [5,14]:…”

“…[4][5][6], metallic sulfides (CdS, Cd-Zn-S…etc.) [7][8][9], alloys materials and organo-metal complexes of magnesium(II), calcium(II), zin(II), nickel(II), Cobalt(II), copper (II)…etc) [10][11][12][13][14][15][16][17][18][19][20][21][22].…”

“…[3,14]. However, the SILAR method is a simple technique, it can be proved very good homogeneity and thickness control of multilayer deposed materials [11][12][13][14][15][16].…”

Adsorption Isotherm Models, Kinetics Study, and Thermodynamic Parameters of Ni(II) and Zn(II) Removal from Water Using the LbL Technique

“…17 The synthesis of an optically active nanomaterial such as nanosized Zn[(NO 2 ) 2 -8HQ) 2 ] and Mg[(NO 2 ) 2 -8HQ) 2 ] was also reported. 18,19 8-Hydroxyquinoline (8HQ) has been widely applied in the LbL technique because it is a potent chelating agent for a series of metal ions. 20 This technique works on the basis of the surface deposition of 8HQ molecules on a selected substrate, followed by the deposition of metal ions for the formation of the metal-8HQ complex.…”

“…Electrochemical biosensors as LbL films of poly­(allylamine hydrochloride) and naturally occurring humic acids were deposited onto ITO electrodes to detect low concentrations of pentachlorophenol . The synthesis of an optically active nanomaterial such as nanosized Zn­[(NO 2 ) 2 -8HQ) 2 ] and Mg­[(NO 2 ) 2 -8HQ) 2 ] was also reported. , …”
