(a) UV-Vis absorption and (c) fluorescence spectra of TPPh, TTPy, OTPy and TOPhP in THF (1 × 10−5 M) solution. (e) Absorption spectra and (g) fluorescence spectra of TPPh, TTPy, OTPy and TOPhP nanoparticles in water. Panels (b) and (f) show the corresponding absorption colors in THF and water, panels (d) and (h) show the corresponding emission colors in THF and water under the UV light (λ=365 nm).
