The present invention provides: quantum dots that are encapsulated by means of a siloxane having a C4 or higher alkyl group; a composition comprising same; and a device in which the composition is used. When the encapsulated quantum dots are used, the quantum efficiency and the dispersion stability can be improved. Cette invention concerne : des boîtes quantiques qui sont encapsulées au moyen d'un siloxane contenant un groupe alkyle C4 ou supérieur ; une composition les contenant ; et un dispositif utilisant ladite composition. Quand les boîtes quantiques encapsulées selon l'invention sont utilisées, le rendement quantique et la stabilité de dispersion peuvent être améliorés.
