We report on the systematic characterization of the optical properties of diamond color centers
based on Pb impurities. An ensemble photoluminescence analysis of their spectral emission was
performed at different excitation wavelengths in the 405–520 nm range and at different
temperatures in the 4–300 K range. The series of observed spectral features consist of different
emission lines associated with Pb-related defects. Finally, a room-temperature investigation of
single-photon emitters under 490.5 nm laser excitation is reported, revealing different spectral
signatures with respect to those already reported under 514 nm excitation. This work represents a
substantial progress with respect to previous studies on Pb-related color centers, both in the
attribution of an articulated series of spectral features and in the understanding of the formation
process of this type of defect, thus clarifying the potential of this system for high-impact
applications in quantum technologies.
