(a) UC luminescence spectra of samples with different Ag concentration under the excitation of 980 nm laser diode: the inset is absorption spectra of samples by modulating the Ag concentration. (b) Room temperature luminescence decay curves of 4S3/24I15/2 (Er3+) transition of the 0 Ag, 0.1 Ag, 0.3 Ag, 0.5 Ag, and 0.7 Ag samples.
