摘要

Irradiation effect Luminescence Nanostructures Visible and ultraviolet spectrometers Materials Science (all) Condensed Matter Physics
We show that by using different x-ray irradiation times of BSA-coated Au nanoparticles (NPs) we can change their ultraviolet-stimulated photoluminescence and shift the spectral weight over the visible spectral range. This is due to the interplay of two emission bands, one due to BSA and the other related to gold. The emission properties did not change with time over a period of several months.
