英文摘要	Al2O3: Er3+/Yb3+transparent ceramics codoped with Zn2+ions with intense upconversion and near infrared emission were prepared by conventional solid-state reaction and vacuum and hot isostatic pressing sintering. The effects of Zn2+incorporation to the structure, transparent, upconversion and NIR luminescence were discussed in detail. The as prepared Al2O3ceramics exhibited a total transmittance of ~ 75% in infrared regions (800–3300 nm) and ~ 50% in visible regions (500–800 nm). Under the excitation of a 980 nm laser diode, the as prepared Al2O3ceramics displayed two tense upconversion emission peaks of a green one centered at 550 nm and a red one centered at 660 nm and a tense near infrared emission peak centered at 1.532 µm, characteristic of Er3+emission. Compared with Er3+/Yb3+doped only, Zn2+codoped Al2O3:Er3+/Yb3+transparent ceramics showed higher upconversion and near infrared emission of ~ 11 times and ~ 4 times, respectively. The enhancement mechanism due to incorporation of Zn2+ions was also discussed in detail. © 2018 Elsevier B.V.
