摘要： This invention relates to luminescent materials for ultraviolet light or visible light excitation containing lead and/or copper doped chemical compounds. The luminescent material is composed of one or more than one compounds of aluminate type, silicate type, antimonate type, germanate/or germanate-silicate type, and/or phosphate type. Accordingly, the present invention is a good possibility to substitute earth alkaline ions by lead and copper for a shifting of the emission bands to longer or shorter wave length, respectively. Luminescent compounds containing copper and/or lead with improved luminescent properties and also with improved stability against water, humidity as well as other polar solvents are provided. The present invention is to provide lead and/or copper doped luminescent compounds, which has high color temperature range about 2,000K to 8,000K or 10,000K and CRI over 90.

摘要： In one aspect, compositions comprising Group III-V nanowires, and methods of making such nanowires, are described herein. In some embodiments, a composition described herein comprises one or more core-shell nanowires comprising a core and a first shell surrounding or substantially surrounding the core. The core is formed from GaAs, and the first shell is formed from GaAs(1-x-y)SbxNy. Additionally, x is 0.08-0.15, and y is 0.005-0.035. In some cases, x is 0.10-0.17, and/or y is 0.01-0.02. Further, the nanowires have an average emission maximum of 1.25-1.35 μm. Moreover, in some instances, the nanowires further comprise a second shell surrounding or substantially surrounding the first shell. The second shell, in some embodiments, is formed from a Group III-V material such as GaAs. For example, in some instances, the nanowires have the structure GaAs/GaAs(0.82-0.9)Sb(0.09-0.15)N(0.005-0.033)/GaAs.
