We have performed soft X-ray spectroscopy in order to study thephotoirradiation time dependence of the valence band structure and chemicalstates of layered transition metal nitride chloride TiNCl. Under the soft X-ray irradiation, the intensities of the states near the Fermi level ($$E_{rm F}$$)and the Ti$$^{3+}$$ component increased, while the Cl 2$$p$$ intensity decreased. Ti2$$p$$-3$$d$$ resonance photoemission spectroscopy confirmed a distinctive Fermiedge with Ti 3$$d$$ character. These results indicate the photo-inducedmetallization originates from deintercalation due to Cl desorption, and thusprovide a new carrier doping method that controls the conducting propertiesof TiNCl.
