Special Issue Information

Dear Colleagues,

Owing to the continuous breakthroughs in light-emitting diodes (LEDs) during the past few decades, LEDs are playing an increasingly critical role in solid-state lighting, flat-panel displays, and optical communications. Despite their success in some fields, LEDs are still extensively investigated with the aim of achieving high brightness, long lifetime, low power consumption, and low fabrication cost. To realize this objective, developing new light-emissive materials and designing novel device configurations are essential. Accordingly, this Special Issue seeks to showcase research papers, communications, and review articles that focus on 1) the synthesis of emerging light-emissive materials (e.g., perovskites, thermally activated delayed fluorescence (TADF) materials, and quantum dots), 2) fabrication of novel LEDs, 3) new integration techniques for LEDs, and 4) theoretical modeling of LEDs.

We look forward to receiving your submission.

Abstract
A titanium–indium tin oxide (TITO) multilayer reflector was investigated to improve the light efficiency of high-power, near-infrared, light-emitting diodes (NIR-LEDs). The TITO/Ag was fabricated by combining a patterned TITO and an omnidirectional reflector (ODR). For fabricating a high-power NIR-LED, the wafer bond process [...] Read more.
A titanium–indium tin oxide (TITO) multilayer reflector was investigated to improve the light efficiency of high-power, near-infrared, light-emitting diodes (NIR-LEDs). The TITO/Ag was fabricated by combining a patterned TITO and an omnidirectional reflector (ODR). For fabricating a high-power NIR-LED, the wafer bond process required the TITO reflective structure, which has patterns filled by AlAu contact metal, bonded directly to the Ag reflector deposited on the silicon wafer. Among Ag-based single- and multilayer reflectors, the TITO/Ag showed the highest reflectance (R = 96%), which was favorable for wafer-bonded high-power NIR-LEDs. Therefore, the TITO/Ag reflector enabled the production of wafer-bonded NIR-LED chips that exhibit superior output performance (190 mW) compared with conventional cases using a single Ag reflector.

In this article, red and green perovskite quantum dots are incorporated into the pixels of a flexible color-conversion layer assembly using microfluidics. The flexible color-conversion layer is then integrated with a blue micro-LED to realize a full-color display with a pixel pitch of 200 μm. Perovskite quantum dots feature a high quantum yield, a tunable wavelength, and high stability. The flexible color-conversion layer using perovskite quantum dots shows good luminous and display performance under different bending conditions; is easy to manufacture, economical, and applicable; and has important potential applications in the development of flexible micro-displays.
