The interest to foster plasmonic applications at energies
in the
ultraviolet has escalated research initiatives in clusters of unconventional
plasmonic materials like aluminum and indium, for which the surface-plasmon
resonance appears above the ionization potential. Naturally, the quantum
mechanical description calls for the incorporation of the ionization
process, thereby making the <i>ab initio</i> calculations
challenging. We present a robust approach within the time-evolution
formalism of the time-dependent density-functional theory to calculate
surface plasmon resonances in the continuum of metal clusters. Using
the much studied Al13− as a system of reference, we show that
accurate description of the continuum and of the ionization of the
cluster allows to capture a broad surface-plasmon in the ultraviolet.
Application of this approach in aluminum clusters has given the size-dependent
evolution from discrete spectral features in Al<sub>6</sub> to the
surface-plasmon in larger clusters in the deep ultraviolet.
