“…The obtained ε value at λ max was close to those of aqueous Ru 2+ (1.42 × 10 4 L mol –1 cm –1 at 453 nm) and Ru 2+ /SSA (1.43 × 10 4 L mol –1 cm –1 ). , Representative absorption spectra of An-Py 2+ /Ru 2+ /SSA with adsorbed amounts of An-Py 2+ and Ru 2+ of 25% CEC are shown in Figure (blue line). Based on area coverage, the SSA surface was almost fully covered by An-Py 2+ and Ru 2+ under these conditions (Ru 2+ and An-Py 2+ = 25% CEC) . The absorption spectra of An-Py 2+ /SSA and Ru 2+ /SSA and the calculated spectrum (simple sum of those of An-Py 2+ /SSA and Ru 2+ /SSA) are illustrated in Figure (green line) as a comparison.…”

“…The normalized emission spectrum of independently prepared An-Py 2+ on SSA (An-Py 2+ /SSA, An-Py 2+ = 0.1% CEC) and the absorption spectrum of Ru 2+ on SSA (Ru 2+ /SSA, Ru 2+ = 25% CEC) are shown in Figure S1. The spectral overlap integral ( J ) was estimated to be 1.7 × 10 14 M –1 cm –1 nm 4 , which is approximately twice those observed in earlier studies for Py 4+ /SSA and Ru 2+ /SSA systems. , This J value suggests efficient energy transfer from An-Py 2+ to Ru 2+ on SSA. The absorption spectra and corresponding Lambert–Beer plot of An-Py 2+ /Ru 2+ /SSA at the maximum absorption wavelength (λ max ) of the Ru 2+ component (454.5 nm) with different loading amounts of Ru 2+ (Ru 2+ = 0–25% CEC) are shown in Figure S2.…”

“…The hybridization of an amphiphilic Ir(III) complex with various kinds of clay minerals was investigated [16,[22][23][24]. In the case of synthetic saponite, for example, the emission was enhanced through the hybridization [25][26][27][28][29]. Similar enhancement was also realized by adsorbing Ir(III) complexes on a colloidal particle of synthetic saponite [30,31].…”
