Lead Halide Perovskite Nanocrystals - A New Promise for Light Emitting Devices
Perovskites structured materials have attracted scientific and technological interest in the last four years.
Recent studies have shown that these materials could deliver high photoluminescence efficiency at any
desired wavelength in the visible spectrum. Mirko Prato and Francesco Di Stasio, Technologist and
Marie Curie Fellow of the Institute of Photonic Sciences at the Istituto Italiano di Tecnologia focus on the
application in single color LEDs (red, green and blue) and white emitting color-converting layers. They
discuss what limits their application in everyday technology like toxicity and limited functional stability.

From Component to System, Andreas Weisl, CEO at Seoul Semiconductor Europe GmbH
The history of Light-Emitting Diodes
(LED) is quite short compared with
some other electronic device industries.
However, it has changed and
revolutionized the entire world of light
within a very short period of time. The history of Light-Emitting Diodes (LED) is quite short compared with some other electronic device industries. However, it has changed and revolutionized the entire world of light within a very short period of time.

Tech-Talks BREGENZ - Dr. Rubén D. Costa, Group Leader, University of Erlangen-Nuremberg
Light quality and costs of LED systems remain an important topic even though big improvements have
been made. New approaches are always welcome and stir up hope. It was exactly a year ago that LED
professional published the article by Dr. Rubén D. Costa, Liebig Group Leader at the University of
Erlangen-Nuremberg, about his amazing new „Bio-Hybrid“ white LED approach. At LpS 2016 his
presentation on the latest research results and improvements also won him the LpS 2016 Scientific
Award. Consequently, we just had to invite him to a Tech-Talk Bregenz! In the interview below he gives
us some interesting background information about why he started the project, how it works and what
he expects in the future. He also gives us his views on LEDs and lighting in general.

Thermal Management of an LED Light Source for Microscopes
Thermal management is a challenge for every LED and LASER solution. Microscope lighting solutions
have some very critical requirements, especially if they concern medical applications. ESCATEC in
Heerbrugg, Switzerland has a lot of experience in that field and covers all relevant technical disciplines.
Wolfgang Plank, head of the MOEMS Future Laboratory and cleanroom, and Gerd Harder, Key Account
Manager, give insights on the design process, thermal simulation and production of an LED light source
for Leica Microsystems’ Ophthalmic Microscope Proveo 8.

Nanorod LEDs with Two Functions Could Make Multifunctional Displays
Cellphones and other devices could soon be controlled with touchless gestures and charge themselves using ambient light, thanks to new LED arrays that can both emit and detect light. Made of tiny nanorods arrayed in a thin film, the LEDs could enable new interactive functions and multitasking devices. Researchers at the University of Illinois at Urbana-Champaign and Dow Electronic Materials in Marlborough, Massachusetts, report the advance in the Feb. 10 issue of the journal Science.

International FLINGO Project to Improving the Properties of LEDs Has Started
In view of the growing demands placed on the electrical, optical and thermal functionality of LEDs, more and more attention is being paid to research into new material properties. The purpose of the FLINGO project is therefore to develop new materials (layers in particular) and processes to improve the characteristics of LEDs, such as efficiency and durability. The intention is to maintain and improve market leadership in innovative LED products. As the project coordinator, Osram Opto Semiconductors is working since February 2017 with renowned universities, research institutes and companies. The German Federal Ministry for Education and Research is sponsoring the FLINGO project (Functional Inorganic Layers for Next Generation Optical Devices) as part of the M-ERA.NET EU initiative.
