1. Core-shell In1-xGaxP nanocrystals, each comprising an In1-xGaxP core consisting of only In1-xGaxP alloy and having a surface, where 0.2≤x≤0.85, and a ZnS shell on the surface of the In1-xGaxP core, wherein the core-shell In1-xGaxP nanocrystals absorb blue light and emit green or red photoluminescence, the green or red photoluminescence characterized by a photoluminescence peak maximum in the range from 490 nm to 640 nm and a photoluminescence peak full-width-half-maximum of 60 nm or lower at a temperature of 25° C.
