Abstract
Tellurium compound nanoparticles, including: an element M1 where M1 is at least one element selected from Cu, Ag, and Au; an element M2 where M2 is at least one element selected from B, Al, Ga, and In; Te; and optionally an element M3 where M3 is at least one element selected from Zn, Cd, and Hg; wherein a crystal structure of the tellurium compound nanoparticles is a hexagonal system, the tellurium compound nanoparticles are of a rod shape and have an average short-axis length of 5.5 nm or less, and when irradiated with light at a wavelength in a range of 350 nm to 1,000 nm, the tellurium compound nanoparticles emit photoluminescence having a wavelength longer than the wavelength of the irradiation light.
