a Schematic illustration of the two kinds of PNC@AINO according to the type of PNC. The M-PNC is physically dispersed in the AINO, while the V-PNC can be chemically anchored to polymer chains of the AINO, due to crosslinkable vinyl groups in its ligands. b Photographs of the nanocomposite arrays from the pure AINO (left) to PNC@AINO with low concentration (0.2 mg ml−1, middle) and saturated concentration (12 mg ml−1, right). First row is the M-PNC@AINO, while the second row is the V-PNC@AINO, under daylight (upper) and UV light (lower). Scale bar = 1 cm. c PL spectra of the nanocomposites from precursor state with low concentration (dot line) to its gel state (dash line), and gel state with saturated high concentration (solid line). d PLQE and FWHM of the nanocomposites as a function of PNC concentration. Values represent the mean and standard deviation (n = 3). e Stress–stretch curves of the AINO, M-PNC@AINO, and V-PNC@AINO. Solvent and polymer volume concentration of each specimen are phenyl octane and 0.65, respectively. The PNC concentration of the M-PNC@AINO and V-PNC@AINO is 12 mg ml−1. f Photographs of the luminescent V-PNC@AINO stretched to 11 times its original length under UV irradiation. Scale bar = 2 cm.
