Abstract Visible photoluminescence (PL) has been observed from rare earth (Tm, Sm and Dy)-doped AlN films grown by radio-frequency magnetron reactive sputtering. X-ray diffraction indicates that the films are c-axis-oriented hexagonal wurtzite type structure with an average crystal size of about 80--110nm. Room-temperature PL spectra indicate that the blue emission is due to the transition of 1D2 to 3F4 and 1G2 to 3H6 intra 4f electron of Tm3+, the yellow emissions of AlN:Sm are due to 4G5/2 to the 6HJ (J = 5/2, 7/2, 9/2, 11/2) and the reddish emissions of AlN:Dy correspond to the 4F9/2 to 6HJ (J = 15/2, 13/2, 11/2 and 9/2) and 6F11/2 transitions.

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.
