The invention belongs to the technical field of photoelectron information, particularly relating to a nanocrystal reinforced rare earth doped tellurate luminous film material and a preparation method thereof. The tellurate luminous film material comprises the following components: 50-95 mol% of TeO2, 0-20 mol% of TiO2, 0-10 mol% of Al2O3, 0-30 mol% of ZnO, 1-10 mol% of Na2O, 1-10 mol% of Re2O3 and 0-30 mol% of M, wherein Re is rare earth element and is one or a plurality of Pr, Nd, Sm, Eu, Tb, Ho, Er, Tm and Yb, and M is noble metal element and is one or a plurality of Ag, Au and CU. The tellurate luminous film material utilizes organic alkoxide or inorganic salt of the components through a non-hydrolysis sol-gelation method, and the tellurate luminous film material is prepared on the optical glass substrate according to the composition range and certain technical condition. The invention has simple preparation method and low cost, and the obtained film material is even and transparent, and fluorescent output can be greatly enhanced by laser pump excitation. The film material can be used in the fields, such as optical information record, display, treatment and the like.
