Improving on LEDs: Osram launches FLINGO project

Technology News |
By Julien Happich


In particular, the FLINGO project (Functional Inorganic Layers for Next Generation Optical Devices) will focus on the functional layers and processes to improve the characteristics of LEDs, such as their efficiency and durability.

In the course of the FLINGO project different deposition methods for thin films such as atomic layer deposition, spray pyrolysis and the sol gel process for manufacturing high-quality LED light sources are to be investigated and combined.

Under the leadership of Dr. David O’Brien from Osram Opto Semiconductors, the project partners will be working on the entire bandwidth of new component properties – including extended lifetime, smaller electrical layer resistance and improved light extraction. These require new materials and innovative or adapted deposition processes.

In addition to project coordinator, Osram Opto Semiconductors, the FLINGO project involves Uninova from the New University of Lisbon, the Finnish thin film technology company Picosun Oy, the Fraunhofer Institute for Silicate Research ISC in Würzburg and Vilnius University.


Fraunhofer ISC provides support with its know-how in the development of new inorganic layer systems which are to be used as the matrix for sensitive converter materials.

Uninova will add its expertise in the manufacture of highly transparent and highly conductive layers which are needed for the p-contact in the LEDs.

Picosun Oy is developing atomic layer deposition (ALD) processes and new materials to ensure conformal coating of even heavily structured surfaces.

The Institute for Applied Research at Vilnius University provides specialist knowledge in the development and characterization of non-destructive material properties and will analyze the new layers and layer systems developed in the FLINGO project.

As an end user of the technologies developed in FLINGO, Osram Opto Semiconductors will ultimately transfer the new thin layers and layer systems to its LEDs to test them for their suitability for the mass market.

FLINGO will be sponsored throughout its intended duration until January 2020 by the German Federal Ministry of Education and Research as part of the M-ERA.NET EU program.
