Near-infrared organic imaging device with photon-to-photon upconversion efficiency of > 20%
Shun-Wei Liu
We have demonstrated a simple structure for achieving an efficient organic upconversion device with a high conversion efficiency under a near-infrared light of < 1 mW/cm2. In consequence, various novel electronics related to perspective eyeglasses could be realized successfully in future based on the concept of such device.

Surface Engineering Purification Process for Perovskite CsPbBr3 Quantum Dots and Applications in Light Emitting diodes
Yen-Hung Tien;Po-Wei Tseng;Ching-Ho Tien;Lung-Chien Chen
High-quality perovskite CsPbBr3 quantum dots (PeQDs-CsPbBr3) were prepared using hot-injection method. The photoluminescence of PeQDs-CsPbBr3 films was characterized by narrow line-width emission of 28 nm, with high quantum yields of about 91.7%. Finally, the PeQDs-CsPbBr3 LEDs exhibits a maximum luminance of 488 cd/m2 and maximum external quantum efficiency of 0.14%.

Enhancement of the Blue Emission Intensity in White OLEDs with Double Emitting Layers
Jian-Yang Lin;Guan-Wei Lin
In this study, double emitting layers have been used for fabricating the white organic light-emitting diodes (WOLEDs). The first emitting layer has orange emission, and the other emitting layer has blue emission. Different proportions of the double emitting layers have been examined to enhance the blue emission of the WOLEDs.

Synthesis and Characterization of advanced inorganic perovskite quantum dots applied for warm white-light-emitting devices
Yueh-Chien Lee;Liang-Yih Chen;Kwong-Kau Tiong;Jui-En Hung
In this work, we attempt to develop an efficient reaction with optimized synthesis parameters for preparing highly luminescent inorganic CsPb(I/Br)3 quantum dots doped with Mn. The recombination mechanism and the dynamical behaviors of photoexcited carriers of CsPb(I/Br)3:Mn QDs are investigated by temperature-dependent photoluminescence and time-solved photoluminescence, respectively.

Investigation of Quantum Dots White OLEDs with SiO2 Periodic Mesh
Haou-Chun Wang;Po-Sung Su;Chih-Hsun Lin;Ching-Ting Lee
The quantum dots white organic light-emitting diodes (QDs WOLEDs) with SiO2 film and SiO2 periodic mesh were fabricated. The SiO2 film and SiO2 periodic mesh could prevent moisture and enhance the contact surface area, respectively. Consequently, the current density, luminous efficiency, and life time of QDs WOLEDs were improved.
