Characterization of the NaYF4 NPs. (a) Representative TEM image of the NaYF4 NPs. (b) XRD pattern of the synthesized NaYF4 NPs (top panel); the reference XRD pattern of β-NaYF4 (JCPDS: 16-0334) is shown in the bottom panel. (c) Room-temperature OTN-NIR emission spectrum of the NaYF4 NPs in cyclohexane at a concentration of 11 mg/mL under 980-nm laser excitation. The laser power was 4.22 W.
