Fig. 3

a DLS size distribution of Eu3+-L (black curve) and Eu3+-L-OF-1 (red curve) ([Eu3+] = 1.4 × 10−4 M, [L] = [OF-1] = 2.1 × 10-4 M). b UV–Vis spectral changes and corresponding photographic images of Eu3+-L-OF-1 and Eu3+-L-CF-1 with alternating 300 nm UV and >450 nm visible light irradiation in water for up to 60 s each time ([Eu3+] = 1.4 × 10-5 M, [L] = [OF-1] = 2.1 × 10−5 M).
