Photophysical properties of the pSAStide-terbium and SAStide-terbium complexes.

Peptide	λ_Ex	τ_H2O	τ_D2O	q	φ
pSAStide	266	2.02	2.44	0.12	0.34
SAStide	275	1.88	2.92	0.66	N.D.

λ _Ex = maximum excitation wavelength; τ_H2O⁻¹ = luminescence decay in the presence of H₂O; τ_D2O⁻¹ = luminescence decay in the presence of D₂O; q = number of H₂O ligands in inner coordination sphere at equilibrium; φ = quantum yield.
