Abstract :
Intense emission peaking at 2.18 μm was successfully obtained from erbium upon carefully designed engineering of its glass host both thermally and spectroscopically. Highly localized crystallization of erbium sites is verified by micro Raman and micro-PL along with TEM characterizations.
