文摘

Er3+ -doped phosphate based glasses were prepared by melt quenching method. XRD, DTA-TGA analyses were carried out to know glassy nature and thermal properties. PL spectra and PL lifetime were recorded for all the samples at 1.54 μm. Optical amplifier parameters are greater than the other reported glasses. The obtained results are most favorable for short-length amplifiers.
