1. A semiconductor nanocrystal particle comprising
zinc,
tellurium, and
selenium,
wherein a mole ratio of the tellurium to the selenium is less than 0.01:1,
wherein the semiconductor nanocrystal particle emits blue light comprising a maximum peak emission at a wavelength of greater than or equal to 449 nanometers (nm) and less than or equal to about 470 nanometers (nm), and
wherein the maximum peak emission has a full width at half maximum of less than or equal to about 40 nm or wherein the semiconductor nanocrystal particle is configured to show a quantum efficiency of greater than or equal to about 60%.
