Role of trivalent La and Nd dopants in lattice distortion and oxygen vacancy generation in cerium oxide nanoparticles
TL;DR: In this paper, nanocrystalline Ce1−xRExO2−y (RE=La and Nd) powders were synthesized with a controlled size in the range of 3-5nm using microemulsion technique.

Robert Stegeman,Clara Rivero,Kathleen Richardson,George I. Stegeman,Peter J. Delfyett,Y. Guo,April Pope,Alfons Schulte,Thierry Cardinal,Philippe Thomas,J. C. Champarnaud-Mesjard +10 more
TL;DR: Several different compositions of tellurium-thallium glasses were fabricated and tested for their Raman gain performance and the maximum Raman Gain experimentally obtained was higher than the peak Raman loss of fused silica.

Low-frequency vibrational excitations in a niobium-phosphate glass for Raman gain applications
TL;DR: In this paper, the authors present measurements of the Raman spectrum of binary niobium-phosphate glasses in the frequency range from 5 to 1300 cm −1, showing that the spectra of these glasses show a low-frequency enhancement of the vibrational density of states (Boson peak) suggesting a significant gain profile for application in Raman amplifiers.
