The invention belongs to the field of materials, and particularly relates to a metal ion doped rare earth phosphate red light conversion agent and a preparation method and application thereof. The general chemical formula of the metal ion doped rare earth phosphate red light conversion agent is M3Y (1-x) (PO4) 2: xEu < 3 + >, x is more than 0 and less than or equal to 0.2, x represents mole fraction, and M is one of elements Na, K, Mg, Ca, Sr and Ba. The phosphate red light conversion agent has a nano-scale grain size, effectively improves the luminous intensity, has good stability, and can be used in the field of light conversion agricultural films. According to the preparation method, a planetary ball milling method is adopted, the preparation process is simple and easy to operate, large-scale copying can be achieved, and industrial production is achieved. 本发明属于材料领域，具体涉及一种金属离子掺杂的稀土磷酸盐红光转光剂及制备方法和用途。本发明的金属离子掺杂的稀土磷酸盐红光转光剂，其化学通式为M3Y(1-x)(PO4)2:xEu3+，其中0<x≤0.2，x代表摩尔分数，M为元素Na、K、Mg、Ca、Sr、Ba中的一种。本发明的磷酸盐红光转光剂，晶粒尺寸为纳
