Persistent spectral hole burning studies of europium-doped sodium germanate glass
Rajamohan R. Kalluru, Chandra R. Pulluru, Bommareddi Rami Reddy
Persistent spectral hole burning has been observed in europium-doped sodium germanate glass. Hole-burning efficiency increased by 85% when the glasses were made in a reduced atmosphere, and hole burning was detected even at room temperature. There is evidence for photochemical as well as photophysical hole-burning mechanisms.
