    • According to one embodiment, a semiconductor light emitting device includes an n-type semiconductor layer, a p-type semiconductor layer and a light emitting part. The light emitting part is provided between the n-type semiconductor layer and the p-type semiconductor layer and includes a first light emitting layer. The first light emitting layer includes a first barrier layer, a first well layer, a first n-side intermediate layer and a first p-side intermediate layer. The barrier layer, the well layer, the n-side layer and the p-side intermediate layer include a nitride semiconductor. An In composition ratio in the n-side layer decreases along a first direction from the n-type layer toward the p-type layer. An In composition ratio in the p-side layer decreases along the first direction. An average change rate of the In ratio in the p-side layer is lower than an average change rate of the In ratio in the n-side layer.
    • 根据一个实施例,半导体发光器件包括n型半导体层,p型半导体层和发光部分。 发光部分设置在n型半导体层和p型半导体层之间,并且包括第一发光层。 第一发光层包括第一阻挡层,第一阱层,第一n侧中间层和第一p侧中间层。 阻挡层,阱层,n侧层和p侧中间层包括氮化物半导体。 n侧层的An组成比沿着从n型层向p型层的第一方向减小。 P侧层的In组成比沿着第一方向减小。 p侧的In比的平均变化率低于n侧层的In比的平均变化率。
