To provide an optical wavelength conversion structure.SOLUTION: An optical wavelength conversion structure includes a substrate, a reflective layer, an oxide stack layer, and a wavelength conversion layer. The reflective layer is disposed on the substrate. The oxide stack layer is disposed on the reflective layer. The oxide stack layer has a gas barrier index of about 300-1000, and the gas barrier index is defined by the following numerical formula, where L is a thickness, d is a density, and n is the number of layers. The wavelength conversion layer is disposed on the oxide stack layer.SELECTED DRAWING: Figure 1 【課題】光波長変換構造を提供する。【解決手段】光波長変換構造は、基板、反射層、酸化物スタック層、及び波長変換層を含む。反射層は、基板に設けられる。酸化物スタック層は、反射層に設けられる。酸化物スタック層は、約３００～１０００のガスバリア指数を有し、且つガスバリア指数が【数１】TIFF2024064973000014.tif11170と定義され、ただし、Ｌが厚さであり、ｄが密度であり、ｎが層数である。波長変換層は、酸化物スタック層に設けられる。【選択図】図１
