visible and ultraviolet region meaning in English
可见光区及紫外区
Examples
- This direct band - gap material has a large exciton binding energy ( 60mev ) , which permits excitonic recombination even at room temperature . thus zno is attracting much attention as promising candidates for optoelectric applications in visible and ultraviolet regions
它有较高的激子束缚能（常温下为60mev ） ，使得其在室温下可以发射紫外激光，因此作为新一代的半导体发光材料受到广泛关注。
