From: Phase formation capability and compositional design of β-phase multiple rare-earth principal component disilicates

Composition	FWHM	σ_r

β-(Gd_0.25Ho_0.25Yb_0.25Lu_0.25)₂Si₂O₇	0.93006	0.03055
β-(La_0.25Ce_0.25Yb_0.25Lu_0.25)₂Si₂O₇	6.91337	0.07867
γ-(Dy_0.25Tm_0.25Yb_0.25Lu_0.25)₂Si₂O₇	0.46106	0.01955
γ-(Dy_0.25Ho_0.25Yb_0.25Lu_0.25)₂Si₂O₇	0.67814	0.0215
γ-(Gd_0.25Ho_0.25Yb_0.25Lu_0.25)₂Si₂O₇	1.23961	0.03055
γ-(La_0.25Ce_0.25Yb_0.25Lu_0.25)₂Si₂O₇	10.25844	0.07867

Note: FWHM is defined as the full width at half maximum of the peaks in the mixing energy distribution spectrum, and σ_r is defined as the standard deviation of RE³⁺ cationic radius for a composition.
