(57) The present invention provides a core/multishell semicon ductor nanocrystal comprising
a core and multiple shells, which exhibits a type-I band offset and high photolumines cence
quantum yield providing bright tunable emission cov ering the visible range from about 400
nm to NIR over 1600

… a core/multishell semiconductor nanocrystal comprising a core material made of a III/V
compound and at least two shell materials, wherein a first shell material coats the core material,
a second shell material coats the first shell material, and sequentially each subsequent shell
material coats the preceding … the present invention provides core/shell 1 /shell 2
semiconductor nanocrystals comprising a core material made of a III/V compound and two shell
materials each made of a different II/VI, III/V or III/VI compound wherein the first shell material (ie …
