The invention discloses a preparation method of a triangular prism-shaped rare earth-activated yttrium oxide nano-luminescence material, and belongs to preparation of luminescent nanomaterials.The preparation method comprises the following steps that yttrium nitrate (Y(NO3)3) serving as a yttrium source and rare earth (such as europium, erbium and samarium) nitrate are added into deionized water and triethanolamine (TEOA), full stirring is performed, therefore, the molar concentration of Y<3+> is 0.01 M-1 M, and the molar concentration of rare earth ions accounts for 1%-8% of that of the yttrium ions.Heat preservation is performed for 24-80 h at the temperature of 130 DEG C-200 DEG C through a solvothermal method, and the volume ratio of solvent (TEOA) to the deionized water is (0.1-3):1. 种三角柱状稀土激活氧化钇纳米发光材料的制备方法，属于发光纳米材料的制备。包含以下步骤：将硝酸钇(Y(NO))作为钇源与稀土硝酸盐(铕、铒、钐..)加入去离子水与三乙醇胺(TEOA)中，并充分搅拌，使得Y的摩尔浓度为0.01M?1M，稀土离子摩尔浓度为钇离子的1％?8％。利用溶剂热法经过130?200℃保温24?80h处理。溶剂TEOA与去离子水的体积比为(0.1?3)：1。
