Abstract The performance of red InP and blue ZnTeSe-based quantum dots (QDs) corresponding QD light emitting diodes (QLEDs) has already been improved significantly, whose external efficiencies (EQEs) luminances have exceeded 20% 80 000 cd m −2 , respectively. However, the inferior green InP-based device hinders commercialization full-color Cd-free QLED technology. ease oxidation highly reactive cores leads to high non-radiative recombination poor photoluminescence yield (PL QY) core/shell...
Abstract InP quantum dots (QDs), without heavy metals, show great potential for display and lightening applications. However, achieving efficient InP‐based dot light‐emitting diodes (QLEDs) with extended operational lifetime remains challenging due to unbalanced carrier injection within the device. In this study, polyvinyl pyrrolidone (PVP) is introduced as an intermediate layer between QDs emitting (EML) ZnMgO electron transport (ETL). This designed block excess into simultaneously reduce...
Abstract The external quantum efficiencies (EQE) and luminances of red InP‐based blue ZnTeSe‐based dot light‐emitting diodes (QLEDs) have exceeded 20% 80 000 cd m −2 , respectively, the T 50 @100 (time for luminance decreasing by 50%) operational lifetime QLEDs also 1 h, nearing industrial application standards. However, low EQE, luminance, inferior green restrict their full‐color Cd‐free display lighting applications. large electron injection barrier severe exciton quenching caused defect...
With the advancement toward commercialization of quantum dots (QDs) in field lighting and display, improving performance Cd-free QDs related dot light-emitting diodes (QLEDs) becomes necessary. Thus far, ZnTeSe- InP-based blue red QLEDs has been significantly improved by optimizing emitting materials device structure. However, as one three primary color sources, green still lags behind that QLEDs. Herein, this review discusses latest progress corresponding QLEDs, covering engineering InP...
