波长转换元件、光源装置和投影仪
摘要：
本发明提供波长转换元件、光源装置和投影仪。提供实现了荧光体的高效的发光、以及抑制了温度劣化的波长转换元件。波长转换元件(40)具有：基材(41)；和荧光体层(42)，其含有通过激励光入射而发出荧光的荧光体，设置于基材(41)，荧光体层(42)具有激励光(蓝色光(E))入射的第1面(42i)和与基材(41)相对的第2面(2e)，在第1面(42i)至第2面(42e)之间具有激励光的吸收系数不同的多个区域。
摘要（英）：

A wavelength conversion element, a light source device, and a projector are provided. A wavelength conversion element that achieves efficient light emission of a phosphor and suppresses temperature degradation is provided. The wavelength conversion element includes a base material and a phosphor layer that contains a phosphor emitting fluorescence upon incidence of excitation light and is providedon the base material, in which the phosphor layer includes a first surface on which excitation light (blue light) is incident and a second surface facing the base material, and a plurality of regionswith different absorption coefficients of the excitation light between the first surface and the second surface.
