The structural properties measured by using FTIR show that as the AgCl content increases, the sharp infrared IR absorption peaks were consistently shifted from The X-ray diffraction studies revealed that nickel atoms were successively incorporated into ZnO host matrix without forming any detectable secondary phase. They were characterized by X-ray diffraction, transmission electron microscopy, differential thermal analysis DTA , and Fourier transform infrared FTIR , ultraviolet-visible-near infrared and photoluminescence spectroscopy.

Luminescence of erbium doped tellurite glass containing silver nanoparticles

It has a wide range of applications. The significant enhancement in the luminescence with the increase of AgCl is ascribed to the local field enhancement induced by Ag0 surface plasmon resonance and the energy transfer from fluorescent Ag0? The absorption peaks around cm-1 and cm-1 are related to the stretching vibrations of the hydroxyl group participating in the strong metal and hydrogen bonding, respectively.

The thermal, structural, and optical properties of these glasses were determined and analyzed. Mohan Babu, Suman Shakya, et al. Rajendraprasad Reddy, Mutsumi Sugiyama, K. Mn doped ZnO films with different doping concentration were synthesized by sol gel method using the spin coating technique. Sm Al Salhi, M. Thesls Teknologi Malaysia Institutional Repository. LiNbO3 is an important crystal which has piezoelectric, ferroelectric and electro-optical functions. Zn1-xMnxO thin films are prepared using 2-methoxyethanol solution of zinc acetate dehydrate and manganese acetate tetrahydrate.

The photons of the gas excite electrons from the valence band to the acceptor level, which alters the electron density in these two states. Refractive index and optical properties, Journal of Optoelectronics and Advanced Materials. The Eg of the three samples were obtained as 3.

The observed glass density ranges from 5. All the grown films were polycrystalline with the plane as the preferred orientation and the peak position shifted towards higher diffraction angle with the increase of doping content in the films.

These films achieve tunable band gap characteristics by means etllurite changing the dopant concentration.

Consequently, the refractive index of the substrate changes, which, in turn, modifies the reflectivity of the substrate. Transmission and reflection spectrum of the LiNbO3 samples on the infrared-visible-ultraviolet light have been measured.
