Title: Optical properties of Xe color centers in diamond,
Abstract: Optical properties of color centers in diamond have been the subject of
intense research due to their promising applications in quantum photonics. In
this work we study the optical properties of Xe related color centers implanted
into nitrogen rich (type IIA) and an ultrapure, electronic grade diamond. The
Xe defect has two zero phonon lines at ~ 794 and 811 nm, which can be
effectively excited using both green and red excitation, however, its emission
in the nitrogen rich diamond is brighter. Near resonant excitation is performed
at cryogenic temperatures and luminescence is probed under strong magnetic
field. Our results are important towards the understanding of the Xe related
defect and other near infrared color centers in diamond.
