Extended Data Fig. 2: Photostability of the Eu3+ complex.
From: Ultra-narrow optical linewidths in rare-earth molecular crystals
5D0 photoluminescence (PL) intensity under continuous wave excitation measured at 8 K for the 151Eu3+ isotopically enriched complex. The constant PL signal confirms absence of photobleaching. See SI section 3 for more details.
