“…Zirconium dioxide and ZrO 2 Y 2 O 3 due to their optical properties show many applications in optical components like when high laser power is used in order to minimize the height pulse laser damage threshold and in this cases doping the coatings with nitrogen can improve the refractive index and the protection [9,10]. These kind of coatings have a lot of other applications, such as buer layers for growing superconductors, oxygen sensors, in situations where thermal isolation and chemical protection (TBCs) are required, in bio-applications, etc.…”

Three dierent zirconium oxynitride lms were deposited onto glass and Si (100) substrates at room temperature by pulsed reactive dc magnetron sputtering of a metallic Zr target in an Ar/O2/N2 atmosphere. The structural, compositional and optical properties of the deposited lms were found to depend on the ratio of nitrogen partial pressure to the total reactive gas partial pressure. Energy-dispersive X-ray spectroscopy measurements revealed that as the nitrogen amount increased in the reactive gas the nitrogen content was found to increase in the lm. The lm structure was determined by X-ray diraction. The X-ray diraction patterns of the analyzed samples revealed a strong dependence of the ZrOxNy lm structure on composition. A two layer model, the Bruggeman eective medium approximation and both Drude absorption edge and Lorentz oscillators were used to describe the surface roughness layer and the main ZnOxNy layer, respectively, was used to describe the experimental ellipsometric data. The optical band gap was decreased from 3.56 to 3.45 eV with changing nitrogen content, while refractive index at 650 nm simultaneously was increased from 1.98 to 2.11.

“…Recent iono-luminescence studies [58] on proton irradiated Pr 3+ doped YSZ single crystal show luminescence intensity drop due to non-radiative effects such as local heating, changes in the Pr 3+ ion environment or lattice defects produced by irradiation which acts as killer centers. Luminescence stability [59] of the cubic phase towards proton irradiation can also lead to non-coloration and marginal quenching of intensity in 8YSZ and 12YSZ (cubic). Irradiation with energetic ion beam is bound to introduce residual compressive stresses and hence a lattice distortion.…”
