Photoluminescent ceramics and photoluminescent glass are produced by adding photoluminescent pigment in the producing process of common ceramics and glass . Compared to the common ceramics and glass , the products can glow in the dark after absorb the visible lights , this feature make ceramics and glass use more widely. The material of the photoluminescent ceramics and glass can absorb various visible lights until saturated, then can glow in the dark constantly, unlimited recycle use with a long time after-glow, high lights, which is ten times brightly of the traditional luminescent material (sulfate). The material is free from radioactivity, nontoxic and harmless. The low bright emergency lighting can guide people evacuate orderly under emergency and reduce confusion other than energy-saving. The application of photoluminescent ceramics and glass in the domestic houses and public buildings can not only decorate and beauty the houses and working environment, but also can bring more conveniences to residents with its glow in the dark. Photoluminescent ceramics and glass can release a certain length light wave, which can restrain some kinds of mildews and diseases. This characteristic meets the fashionable and healthy living ideology for modern people by application of the products into kitchen and bath room.
