摘要：
High quality (HQ) hexagonal CdxZn1-xO microdisks, with bandgap from 3.02 eV to 3.22 eV, are grown by chemical vapor deposition (CVD). Structural and composition analyses indicate that the microdisks have hexagonal shape, single crystalline and tunable Cd concentration. By optical pumping, the microdisk functions as whispering-gallery-mode (WGM) resonator. Lasing from ultravoilet (UV, 385 nm) to violet (410 nm) is demonstrated at room temperature. The HQ factor (1283) is observed, only because of the WGM type resonance. The results demonstrate that the lasing characteristics of WGM cavity from CdxZn1-xO microdisks show promising applications in low threshold violet lasers and light emitting devices.
