QUANTUM DOTS AND METHOD FOR PRODUCING SAME, AND MOLDED BODY, SHEET MEMBER, WAVELENGTH CONVERSION MEMBER AND LIGHT-EMITTING DEVICE WHICH USE QUANTUM DOTS

摘要

Provided are: quantum dots capable of suppressing the blackening of a layer containing the quantum dots and positioned directly above a light-emitting element, and also specifically capable of reducing the organic residual material which adheres to the surface of the quantum dots; a method for producing the same; and a molded body, a sheet member, a wavelength conversion member and a light-emitting device which exhibit high light-emission efficiency and use the quantum dots. These quantum dots (5) have a semiconductor-particle core section (7) and a shell section (8) for covering the surface of the core section (7), and are characterized in that the weight loss up to 490°C in a TG-DTA profile falls within 75%. The quantum dots (5) are further characterized in that oleylamine (OLA) is not observed in GC-MS qualitative analysis at 350°C.
