The degree of crystallization (X_c) of 1PO, 2PO, 3PO and 4PO. Φ_P2S7⁴⁻, Φ_{P2S6⁴⁻ (glass+crystal)} and Φ_all of all doped samples are obtained or calculated from Tables S10–S13.

Sample	Φ P2S74−	Φ P2S64− (glass+crystal)	Φ all	X c (%)	Y (%)
1PO	1.6	2.4	6.5	24.6	36.9
2PO	2.5	0.7	6.9	36.2	10.1
3PO	0.3	1.9	4.6	6.5	41.3
4PO	0.4	4.2	6.3	6.3	66.7
