Abstract Highly transparent Yb, Ho doped (YLa)2O3 ceramic was fabricated by conventional ceramic processing with nanopowders. The absorption and emission spectra of the ceramic were investigated. The energy transfer mechanism between Yb3+ and Ho3+ was also discussed. The strong emission band around 2 μm indicated that the Yb–Ho: (Y0.90La0.10)2O3 transparent ceramic is a promising gain medium for the generation of 2 μm laser emissions. The laser operation of Yb–Ho co-doped (YLa)2O3 ceramic at 2.1 μm is first reported.

Online attention
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.
