Enhanced optical properties of germanate and tellurite glasses containing metal or semiconductor nanoparticles
(2013-05-13)
Germanium- and tellurium-based glasses have been largely studied due to their recognized potential for photonics. In this paper, we review our recent studies that include the investigation of the Stokes and anti-Stokes ...

The irst patents and the rise of glass technology
(Brasil, 2016)
Abstract: Background: According to the Guinness Book of Records, the earliest of all known English patents for an invention was granted by King Henry VI in 1449 to Flemish-born John Utynam for making stained glass. The ...
Enhancement of optical absorption, photoluminescence and raman transitions in Bi2O3-GeO2 glasses with embedded silver nanoparticles
(2015-12-01)
The influence of silver nanoparticles (Ag-NPs) on the optical properties of Bi2O3-GeO2 glasses was investigated aiming the characterization of their potential for applications in photonic devices. The samples were prepared ...
Photoluminescence enhancement by gold nanoparticles in Eu(3+) doped GeO(2)-Bi(2)O(3) glasses
(AMER INST PHYSICS, 2009)
We report large photoluminescence (PL) enhancement in Eu(3+)-doped GeO(2)-Bi(2)O(3) glasses containing gold nanoparticles (NPs). Growth of approximate to 1000% in the PL intensity corresponding to the Eu(3+) transition ...
Influence of the temperature on the nucleation of silver nanoparticles in Tm3+/Yb3+ codoped PbO-GeO2 glasses
(Elsevier B.V., 2010-10-01)
The influence of the temperature on the nucleation of silver nanoparticles (NPs) in Tm3+/Yb3+ codoped PbO-GeO2 glasses was studied in this work. The infrared-to-visible frequency upconversion (UC) luminescence of Tm3+ ions ...
