Abstract Erbium-doped glasses showing a wide 1.55μm emission band are reported in a novel heavy metal oxyfluoride glass system SiO$_2$－PbO－PbF$_2$ and their optical properties such as emission spectra, fluorescence lifetime and the refractive index have been investigated. The broad and flat ${}^4$I$_{13/2}$→${}^4$I$_{15/2}$ emission of Er$^{3+}$ ions around 1.55μm can be used as host materials for potential optical amplifiers in wavelength-division-multiplexing network system. We find that with increasing PbF$_2$ content in the glass composition, the fluorescence full width at half maximum and fluorescence lifetime of the ${}^4$I$_{13/2}$ level of Er$^{3+}$ increase, while refractive index and density decrease.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
