The invention relates to a window (1), in particular, a building window, wherein the window comprises photoluminescent material (2) located within the window. The photoluminescent material (2) is preferentially a phosphorescent material provided on a sun blind which is located within a sealed space (5) between two transparent plates (3, 4) of the window. The photoluminescent material can be charged up by daylight and during the night the photoluminescent material can emanate light. Since the photoluminescent material is located within the window, the photoluminescent material is protected against environmental influences, in particular, against humidity, thereby increasing the lifetime of the photoluminescent material and, thus, of the window. The invention relates further to an object, in particular, a building, comprising the window, thereby giving the object an ambient glow.
