Tunable blue-green emission and energy transfer properties in Ba2SiO4:Tb3+ obtained from sol-gel method
(2019-10-01)
Herein, we introduce an adapted sol-gel synthesis of blue-green-emitting phosphors based on Ba2SiO4:Tb3+, which were obtained in a quite-soft calcination condition (1100 °C/2 h) as a monophasic crystalline phase, space ...
CeO2 and CeO2:Pr nanocrystalline powders prepared by the polymeric precursor method: Yellow and red pigments with tunable color
(2020-11-01)
The development of stable and reproducible inorganic pigments is noteworthy for industrial applications mainly considering more intense shades and low toxicity. Among the various candidates to substitute non-hazardous red ...
Color tunability of intense upconversion emission from Er3+-Yb3+ co-doped SiO2-Ta2O5 glass ceramic planar waveguides
(ROYAL SOC CHEMISTRYCAMBRIDGE, 2012)
This work reports on the infrared-to-visible CW frequency upconversion from planar waveguides based on Er3+-Yb3+-doped 100-xSiO(2)-xTa(2)O(5) obtained by a sol-gel process and deposited onto a SiO2-Si substrate by dip-coating. ...

Two-color discrete localized modes and resonant scattering in arrays of nonlinear quadratic optical waveguides
(2005)
We analyze the properties and stability of two-color discrete localized modes in arrays of channel waveguides where tunable quadratic nonlinearity is introduced as a nonlinear defect by periodic poling of a single waveguide ...
