Abstract We investigated the orthogonal solvent of CdSe/ZnS quantum dots in order to deposit poly‐TPD hole transport layer without damages and enhance the performances of QD‐LEDs. Using hexane and heptane as nonpolar organic solvent of QDs does not affect poly‐TPD layer has found. 3 mg/ml in hexane shows highest luminance and current efficiency but creates non‐uniform QD‐layer because lower boiling point of hexane. The last we found that even different concentration of QDs in heptane show similar device performance.
