WAVELENGTH CONVERSION ELEMENT, LIGHT SOURCE DEVICE, PROJECTOR, AND MANUFACTURING METHOD FOR WAVELENGTH CONVERSION ELEMENT
PROBLEM TO BE SOLVED: To provide a wavelength conversion element capable of efficiently taking out fluorescent light.SOLUTION: A wavelength conversion element 41 comprises: a reflecting layer 412 consisting of a sintered body containing metal oxide; and a phosphor layer 411 consisting of a sintered body containing phosphor. The phosphor layer 411 includes: a first surface 411A from which fluorescent light is emitted; and a second surface 411B different from the first surface 411A. The second surface 411B has a bottom surface region 411B1 facing the first surface 411A. The reflecting layer 412 has a first region 412A1 directly coupled to the bottom surface region 411B1.SELECTED DRAWING: Figure 3
【課題】蛍光を効率的に取り出せる波長変換素子を提供する。【解決手段】波長変換素子４１は、金属酸化物を含む焼結体からなる反射層４１２と、蛍光体を含む焼結体からなる蛍光体層４１１と、を備える。蛍光体層４１１は、蛍光が射出される第１面４１１Ａと、第１面４１１Ａと異なる第２面４１１Ｂと、を含む。第２面４１１Ｂは、第１面４１１Ａに対向する底面領域４１１Ｂ１を有する。反射層４１２は、底面領域４１１Ｂ１と直接結合している第１領域４１２Ａ１を有する。【選択図】図３
