Люминофоры Li4Zn(PO4)2:Tb3+, излучающие зеленый свет, синтезированы методом сжигания растворов. Исследованы кристаллическая фаза, форма, морфология и люминесцентные свойства, в том числе кривые затухания. Установлено, что люминофоры Li4Zn(PO4)2:Tb3+ имеют моноклинную структуру с пространственной группой симметрии P21(4), средний размер кристалла ~80 нм. При возбуждении на 250 нм наблюдается зеленое свечение с максимумом при 545 нм, приписываемое переходу 5D4→7F5. Обнаружена зависимость интенсивности излучения от концентрации легирующей примеси.

Novel Li4Zn(PO4)2:Tb3+ green-light-emitting phosphors were synthesized using the combustion process. A thorough investigation was done on the crystal phase, shape, morphology and luminescence properties, including decay curves. With the P21(4) space group, the Li4Zn(PO4)2:Tb3+ phosphors showed a monoclinic structure. It was calculated that the average crystal size was about 80 nm. Under excitation at 250 nm, a strong green emission peak at 545 nm attributed to 5D4→7F5 transition was observed in the present host. It was found that the emission intensity depended on the dopant concentration.
