Provided are semiconductor nanoparticles, a color conversion member including the same, and an electronic device including the same. The nanoparticles comprise: a core containing ZnSe_(1-x)Te_x; a middle shell covering the core and containing at least one of ZnSe and ZnSe_yS_(1-y); and an outer shell covering the middle shell and containing a group II-VI compound, wherein x is 0.2 < x <= 0.5, and y is 0 < y < 1, and emit visible light other than blue. Accordingly, the color conversion member including the semiconductor nanoparticles has excellent light conversion efficiency. ZnSe1-xTex를 함유한 코어(core), 상기 코어를 덮고, ZnSe 및 ZnSeyS1-y 중 적어도 하나를 함유한 중간 쉘(middle shell) 및 상기 중간 쉘을 덮고, II-VI족 화합물을 함유한 외부 쉘(outer shell)을 포함하고, 상기 x는 0.2 < x ≤ 0.5를 만족하고, 상기 y는 0 < y < 1을 만족하고, 청색 이외의 가시광을 방출하는, 반도체 나노입자, 이를 포함한 색변환 부재 및 이를 포함한 전자 장치가 제공된다.
