Figure 2 | Investigation of luminescence kinetics. a, Luminescence decay curves recorded at 980 nm emission under 808 nm pulsed laser excitation. b, Transient absorption (TA) kinetics probed at 834 nm for the respective samples (free ICG, Y@50Yb@ICG, and Er@50Yb@ICG). c, DSL spectra of Er@Y, YbEr@YbNd, YbEr@Nd, and Er@50Yb@ICG) under 808 nm excitation (7.0 W cm-2). d, Comparison of the molar extinction coefficient, quantum yield, and brightness of Er@Y, YbEr@YbNd, YbEr@Nd, and Er@50Yb@ICG in DMF. e, Comparison of 1525 nm emission intensities of unsensitized and ICG sensitization samples (NaErF4, Er@Nd, Er@Er, Er@Y and Er@50Yb) under 808 nm excitation (7 W cm-2).
