We prepared a borosilicate glass, in which the ZrO 2 phase is singly crystallizable, i.e., 15Na 2 O15ZrO 2 30B 2 O 3 40SiO 2 glass, and investigated the texture and morphology of the resulting glass-ceramics. ZrO 2 dendrites with a tetragonal system (hightemperature phase) were developed as initial phase, and the tetragonal phase was transformed to the monoclinic phase (lowtemperature phase) by elongation of the heat-treatment time, and finally the needle-/rod-like crystals on a scale of few hundred nanometers were obtained. The glass-ceramics with monoclinic ZrO 2 showed photoluminescence around 480 nm by excitation in the ultraviolet region. The effect of TiO 2 -addition on the photoluminescent property was also considered.
