Letter

Much interest has been motivated in the conversion of near infrared radiation into visible light in rare earth doped materials because of its potential applications, such as color display, optical data storage, biomedical diagnostics, sensors, under sea optical communications [1, 2, 3, 4, 5]. More recently, white up-conversion emission has especially attracted much attention due to its wide variety of applications, from compact light source to photonic devices [6]. For quite some time, NaYF4 host lattice has been recognized as one of the most efficient up-conversion lattices [7, 8, 9]. Efficient up-converted green and blue emission has been previously reported in Er3+, Yb3+ co-doped and Tm3+, Yb3+ co-doped NaYF4 matrix, respectively [7, 8, 9, 10]. However, no white emission is reported in this efficient host. In this paper, we will report an up-conversion in Er3+, Tm3+ and Yb3+ co-doped NaYF4powder. In this material doped with three kinds of rare earth ions, intense multicolor...
