In the version of this article initially published, y-axis tick marks and units for intensity were not included in Fig. 1a,b. In addition, text was missing after the second sentence of the “Film characterization” section of Methods: “Time-resolved PL spectra were measured by F900 spectrometer with a 375 nm pulsed laser (EPL-375). In the TRPL spectra test, a 377 nm picosecond laser (Edinburgh Instruments EPL-375) was used to excite both the control and target samples. The excitation pulse width was 55 ps with a repetition rate of 200 KHz. The laser spot size was 0.05 cm² and the fluence was around 0.5 μJ/cm². The TRPL was conducted in the mode of time-correlated single photon counting (TCSPC), which is commonly used to test the fluorescence decay lifetime from 10 ps–50 μs.” The Methods and Fig. 1 have been updated in the HTML and PDF versions of the article.
