Abstract This paper reports that the ultraviolet and visible upconversion luminescence from the $^{4}$S$_{3 / 2}$, $^{2}$G$_{9 / 2}$ and $^{2}$P$_{3 / 2}$ levels have been observed in Er$^{3 + }$:YAG following 647.2 nm excitation of the $^{4}$F$_{9 / 2}$ multiple. Upconversion luminescence intensity dependence on pump power was recorded. The measured decay profiles were theoretically fitted by kinetics theory and the basically good agreements were achieved. The results indicate that some energy transfer processes proposed to explain the observed upconversion phenomena are reasonable.

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.
