The invention discloses a rare-earth complex nano luminescent material. The rare-earth complex nano luminescent material is obtained by performing controlled coordination reaction on rare-earth nitrate aqueous solution and mixed aqueous solution of ligand; the formula structure of the rare-earth complex nano luminescent material is [Ln(ad)0.5(phth)(H2O)2], wherein in the formula, Ln is single rare-earth element Eu, Tb or double rare-earth element of combination of Eu and Yb, or combination of Tb and Gd; in the formula, ad and phth are respectively organic ligand adipic acid and phthalic acid; the nano luminescent material is in nano sheet appearance; and the nano sheets can be mutually gathered to form flower-shaped appearance. The single rare-earth material and the double rare-earth doping material are strong fluorescent material; particularly, when the Gd-Tb double rare-earth material contains only 10% of Tb, the luminescent strength is nearly same as that of the pure Tb material. Therefore, the luminescent
