a Relative PL intensity and PLQE of the V-PNC@AINO in ambient air. Inset shows the reference AINO and the nanocomposite from initial state to after 110 days under air exposure. RH relative humidity. b Luminescence behavior of the nanocomposites soaked in DI water clearly differs with the type of PNC. Inset shows the reference AINO (left), M-PNC@AINO (middle), and V-PNC@AINO (right) from initial state to after 30 days in water. c The luminescence increasing behavior of the V-PNC@AINO soaked in water is unaffected by its pH. d Heat markedly decreases the PL intensity and PLQE of the V-PNC@AINO, but they recover under ambient air. e Relative PL intensity and PLQE of the V-PNC@AINO under UV irradiation. f Relative PL intensity and PLQE of the nanocomposites during stretch-and-release cycle test. The concentration of the PNC in all nanocomposites for stability tests is 12 mg ml−1.
