Effects of copper concentration on electro-optical and structural properties of chemically deposited nanosized (Zn–Cd)S:Cu films

Ni-doped Al2O3 sensor for effective SO3 gas adsorption and sensing

“…This transition implies a blue-shift. 35 Excess carriers provided by impurities may fill up the conduction band edge, generating a blue-shift. The blue-shift manifests that Ni + ions distorted the octahedral sites of alumina and this confirmation matches to the XRD results.…”

An Efficient Nonlinear Optical, Magnetic Transition Metal Ion Nickel Doped L- Threonine Cadmium Acetate Monohydrate

“…[6] Ni 2+ donated the excessive carrier which leads to the filling up of conduction band. [7] There was an energy transfer between semiconductor excited states and the 3d level of Ni 2+ ions. [8] The broadening of band gap due to nickel doping leads to blue shift in optical band to band transitions…”

“…The absorption edge of the doped crystal was at 265nm and that of pure was 245nm [2].The band edge create a red shift which was caused by the variation in the [6] Ni 2+ donated the excessive carrier which leads to the filling up of conduction band. [7] There was an energy transfer between semiconductor excited states and the 3d level of Ni 2+ ions. [8] The broadening of band gap due to nickel doping leads to blue shift in optical band to band transitions…”

“…Fig4b.plot of (∝ ℎ )2 versus energy of LTCAM crystal doped Ni 2+The band gap of the grown crystal was 5.02ev and the pure was 4.85ev. The increase in band gap of Ni 2+ doped LTCAM crystal was due to the low concentration of Ni 2+[6] Ni 2+ donated the excessive carrier which leads to the filling up of conduction band [7]. There was an energy transfer between semiconductor excited states and the 3d level of Ni 2+ ions [8].…”

Effect of Cu incorporation on structural and optical properties of nanocrystalline CdSe (nc-CdSe:Cu) thin films

“…Kwak et al [22] have shown that energy band gap and light emission wavelength of CdSe nanocrystals, having Zinc Blende structure, can be tuned by Mg doping ($9.8 at.%). Khare [23] have reported the effect of Cu concentration on the electroluminescent (EL) and photoluminiscent (PL) properties of (Zn-Cd)S nanosized films prepared by CBD technique.…”
