Abstract Nitrogen-rich Ca- -sialon: Eu2+ phosphors with saturated calcium solubility are synthesized through a solidstate reaction (SSR) at 2173 K with stable alloy and nitride as the starting materials. The Ca1.83-1.5xSi8.34 Al3.66OxN16-x: xEu phosphors have intensive orange emissions, whose peaks are located at approximately 585–600 nm, and the emission wavelengths tend to shift toward the red region when the Eu concentrations increase from 0.5% to 18% (mole percentage). When the Eu concentration is equal to 9%, the phosphors suffer from concentration quenching. The low-temperature photoluminescence properties indicate that Ca1.83-1.5xSi8.34Al3.66OxN16-x: xEu phosphors show excellent thermal quenching. The crystal structures of Ca1.83-1.5xSi8.34Al3.66OOxN16-x: xEu are also investigated, and are found to have nitrogen-rich compositions with saturated calcium cations at the interstitial sites of the α-sialons. In addition, the influencing factors of -sialons with different compositions on the crystal lattice are discussed in detail.

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.
