Abstract This paper reports the upconversion luminescence phenomenon of crystal ErP5 O14 in ultraviolet to blue-green wave range induced by red DCM dye laser. The upconversion passage of each upconversion fluorescence is confirmed. It is found that the upconversion mechanism is mainly non-resonant upconversion energy transfers between rare earth ions when laser wavelength is near 650 nm. It is very interesting that the non-resonant upconversion energy transfer is achieved directly through a kind of coupling state of rare earth ion cluster and the ions do not exchange their phonon energy with crystal lattice.

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.
