Figure 3

Absorption (A) and emission (B) spectra of the PTE solution (-■-; 12.5 μM in acetone) and particles (-▲-; effective PTE concentration of 12.5 μM) in the absence of polymer matrix. Absorption (C) and emission (D) spectra of the nanoprecipitated pure PTE (-●-; 12.5 μM) and PMMA–PTE (-⧫-; effective PTE concentration of 12.5 μM) particles in aqueous solutions under normalized conditions. Confocal images of PTE crystals (E) obtained from the acetone solution through evaporation; nanoprecipitated PTE (F) and PMMA–PTE (G) nanoparticles.
