摘要：

In this paper, we introduced a bluish violet-emitting phosphor Ca3Al4ZnO10:Ti (IV) (CAZO:Ti4+) synthesized by high-temperature solid-state reaction. Upon 265nm excitation, a broad emission band spanned from 300nm to 500nm and centered at 370nm was observed. In addition, the effects of flux and charge compensation to photoluminescence properties of CAZO:Ti4+ were systematically investigated. The results show that 103% improvement of emission intensity was achieved when 1% H3BO3 flux was introduced and 32.8% enhancement of it for 2% Ca2+ vacancies doped as charge compensator. Moreover, the lifetimes, band gap energy, concentration quenching mechanism, as well as electron transition process of CAZO:Ti4+ were discussed. Due to the efficient broad bluish violet emission, this phosphor may find a potential application in mercury vapor-excited fluorescent lamp for plant growth.
