Experimental and theoretical analyses are reported for the spatiotemporal evolution of extreme ultraviolet spectra in laser-produced silver (Ag) plasmas. The time-resolved spectra were acquired 1.5 mm from the target surface. The 4p and 4d excitations of Ag7+–Ag13+ ions were calculated with the aid of multiconfiguration Hartree-Fock calculations. The spectral line distributions of transitions in the dominant 4p and 4d excitation configurations and their variations with the degree of ionization were analyzed. Complex spectral structures were accurately revealed based on the assumption of a normalized Boltzmann distribution among the excited states and a steady-state collision-radiative model. Experimental peak origins were identified by comparing experimental and simulated spectra. These results will provide data for energy-level structures of highly-charged ions of middle- and high-Z elements and their radiative characteristics in plasmas.
