And the common ones in glow in the dark toys are zinc sulfide and strontium aluminate.

而夜光玩具中常见的有硫化锌和铝酸锶。

Strontium aluminate is more expensive, but it has a longer persistence, which means it emits visible light more slowly, and glows longer after being energized.

铝酸锶价格较贵，但持久性较长，这意味着它发出可见光的速度较慢，充电后发光时间更长。
