The invention provides a concave surface fluorescence door lock. A layer of fluorescent material is enclosed on the periphery of the fluorescence door lock, so that the fluorescence door lock can shine at night to enable the position of the door lock to be seen, and since the fluorescence door lock is provided with a concave surface, a key can be inserted into a lock hole along the concave surface conveniently.
