Abstract: We have implemented both the Dornauf–Heber (D–H) model and a brute force statistical (BFS) model to characterize the quenching by neighboring Er and Yb ions of the green and blue emitting states of... read more here.

Abstract: We report on electron spin relaxation measurements of Er3+ dopants in a Y2SiO5 crystal using an electron paramagnetic resonance spectrometer based on a Josephson bifurcation amplifier. We observed the change in the induced flux as… read more here.
