Commonly referred as phosphorescence, persistent luminescence is the emission of light by a phosphorescent material after an excitation by ultraviolet or visible light. Such materials would "glow in the dark". Zobraziť viac The mechanism underlying this phenomenon is not fully understood. However, the phenomenon of persistent luminescence must not be mistaken for fluorescence and phosphorescence (see for definitions and ). … Zobraziť viac Persistent luminescence materials are mainly used in safety signs, watch dials, decorative objects and toys. They have also been used as nanoprobes in small animal optical … Zobraziť viac • Luminous paint • Strontium aluminate Zobraziť viac WebThus, Dy3+ forms a substitutional defect complex with borate and acts as an acceptor-type defect center. These defects trap the hole generated by the excitation of Eu2+ ions and the subsequent thermal release of hole at room temperature followed by the recombination with electron resulting in the long persistent phosphorescence. 展开
