In this work, we develop a technique for the deterministic creation of single organic color centers using in-situ photochemical reaction. As nanotubes are functionalized, discrete photoluminescence (PL) intensity changes corresponding to the formation of individual color centers are observed. By stopping the reaction upon detecting the discrete increase, we are able to deterministically create single color centers. Statistical analysis of PL spectra from individual color centers is conducted to obtain quantitative insight into the distribution of color center types. In addi-tion, this technique allows for position-controlled formation of color centers which is validated by PL imaging. Furthermore, we observe photon antibunching from a color center by performing a photon correlation measurement, showing that single quantum defects can be formed using this technique.
