Luminescent material and luminescent device

According to the light-emitting material, the light-emitting device and the light-emitting material with the cage-shaped structure formed by the quantum dots, the relative density of the quantum dots is improved, exciting light is scattered for multiple times in the light-emitting material after entering the light-emitting material, the scattering path and frequency of the exciting light are reduced, all the quantum dots forming the light-emitting material are fully excited, and the light-emitting efficiency is improved. Therefore, the light conversion efficiency of the quantum dot layer is improved, and the power consumption of the light-emitting device is reduced. 本申请提供了发光材料及发光器件，量子点形成笼状结构的发光材料，提高量子点的相对密度，使激发光在进入发光材料后，在发光材料中进行多次散射，减少激发光经过散射的路径和次数，充分激发组成发光材料的所有量子点，提高激发背光的利用率，从而提高量子点层的光转换效率，并降低发光器件的功耗。
