In this study, luminescence area was tried to be limitted using vector-polarized light in luminescence of Ce:LSO, which is unknown to exhibit the STED phenomenon. As a result, the luminescence of Ce:LSO excited by the soft X-ray of 800 eV photon energy was quenched by the STED light, and the luminescence area was limited centering on the dark point of the STED light.
