The invention discloses a luminous shape-stabilized phase change material and a preparation method thereof. The luminous shape-stabilized phase change material is prepared from the following components in percentage by mass: 1.5 to 10% of chain type liquid crystal polymer at luminous side, and 90 to 98.5% of phase change material. The compound shape-stabilized phase change material has the advantages that while the excellent phase-change energy storage function is realized, the luminous property is realized; the important application prospect is realized in the fields of energy storage fluorescent probes, electronic information, phase change energy-storage luminous clothes and the like.
