Organo lanthanide metal complexes for application as emitting layer in OLEDs

Temperature-dependent structural and optical properties of Sb-doped SnO2 nanoparticles and their electrochemical analysis for supercapacitor application

“…The effect of local structural changes due to Sb doping caused this peak to shift and become more intense, resulting in two obvious bands between 200 and 300 cm −1 . 30,31…”

“…In the B g mode, all 6 Sn-O bonds surrounding the Sn ion contract simultaneously, increasing the repulsive force of the O-O bonds compared to the A 1g mode, where only two bonds contract and the other 4 bonds expand or contract in the opposite directions. The effect of local structural changes due to Sb doping caused this peak to shift and become more intense, resulting in two obvious bands between 200 and 300 cm À1 30,31.…”

Novel mixed ligand coordination compounds of some rare earth metal cations containing acesulfamato/N,N-diethylnicotinamide

“…Today, in biological applications, clinical studies, NLO (nonlinear optics) applications, OLED (organic light-emitting diode) applications, MOF (metal-organic framework) compounds [17][18][19] and even corrosion inhibitors with traditional and toxic chromate-based compounds demonstrated potential for use [20]. On the other hand, the increasing use of rare earth metal compounds in clinical treatments and medicines may raise some negative concerns about their long-and short-term effects in humans and animals.…”

“…Due to their characteristic photophysical and magnetic properties, their use in magnetic and optical devices [1-6], sensor systems [7], biological analysis applications [8-10], and medical diagnostic devices [11][12][13][14] is increasing.Rare earth metal cations prefer to form metal complexes with high coordination numbers with hard Lewis-based donors such as F, O, and N due to their strong Lewis acid character and large ionic radii. The carboxylic acids containing strong Lewis donor atoms, such as O and N, and polyaminopolycarboxylic acids are among the most suitable coordination ligands for rare earth metal cations with 3+ oxidation steps and meet the high coordination numbers needed [15,16].Today, in biological applications, clinical studies, NLO (nonlinear optics) applications, OLED (organic light-emitting diode) applications, MOF (metal-organic framework) compounds [17][18][19] and even corrosion inhibitors with traditional and toxic chromate-based compounds demonstrated potential for use [20].
