Abstract

Colloidal quantum dots are promising next-generation phosphors to enhance the color rendition of light-emitting diodes (LEDs) while minimizing the brightness droop. In order to exploit the beneficial tunability of quantum dots for highly efficient devices, optimization and determination of the performance limit are of crucial importance. In this work, a facile preparation process of red-emission quantum dot films and simulation algorithm for fitting this film with two commercial LED flat lamps to the optimized performance are developed. Based on the algorithm, one lamp improves from cold-white light (8669 K) with poor color rendition (Ra = 72) and luminous efficacy (85 lm/W) to warm-white light (2867 K) with Ra = 90.8 and R9 = 74.9, and the other reaches Ra = 93 ∼ 95. Impressively, the brightness droop is only about 15 ∼ 20% and the luminous efficacy of 68 lm/W is achieved. Furthermore, our device shows reliability over 1000 hours with only PET (polyethylene-terephthalate) films as the barrier, indicating that this auxiliary red-emission film can be easily applied to improve the color rendition of most commercial LED flat lamps.

Fig. 2
Fig. 2 (a) The measured attenuation coefficient α(λ) and photoluminescent (PL) intensity of a dilute QD solution for the test sample (blue and orange solid curves), as well as the fitted red emission of the test QDCCF (dashed curve) with red shift about 6 nm. (b) The energy spectra of the input cold-white light (blue solid curve), the measured warm-white light of the test sample (orange solid curve), and the fitted warm-white light derived from our simulation algorithm (dashed red curve).
Fig. 3
Fig. 3 (a) TEM and (b) HRTEM micrographs of the CdZnSeS/ZnS QDs with emission wavelength of 609 nm. The SAED pattern inserted in (a) shows a zinc-blende structure of the QDs. (c) EDS patterns of the CdZnSeS/ZnS QDs.
Fig. 4
Fig. 4 (a)–(d) Simulation of photometric (LE ratio with respect to the input cold-white light) and colorimetric performance as functions of the film thickness of the QDCCFs, where the wavelength (λR) of red emission is 616 nm for (a)–(b) and 621 nm for (c)–(d), respectively. (e)–(f) The same simulation as functions of λR, with the film thickness being fixed at 80 μm. For comparison, the experimental data are also shown by discrete symbols. The data with zero film thickness correspond to the input cold-white light without the QDCCF.

Fig. 5 (a) Measured energy spectrum (orange solid curve) of the optimized warm-white light of lamp-1 with Ra = 90.8, R9 = 74.9, CCT = 2867 K, and 20% brightness droop compared with the input cold-white light, which is based on our simulation (red dashed curve). The black long-dashed curve represents the reference light with CCT = 2867 K. The QDCCF is prepared with emission wavelength/FWHM (λRR) 621/34 nm and film thickness 80 μm. (b) Spectra of the input day-white light (blue solid curve) and the measured (solid curves) as well as the simulated (dashed curved) warm-white light of lamp-2. (c) Time-dependent PL intensity of the QDCCF, where the red emission keeps initial intensity for over 1000 hours. The insets in (a) and (b) demonstrate the respective optimized devices.
