LEDs (“Light-Emitting Diodes“) are seen in everyday life and are likely to substitute the well established lightbulb, which has been used for more than 100 years. For example LEDs are found in flashlights, automotive dashboards and cellphones, and soon in flat screens.
Advantages of LEDs are a substantial saving of energy, no maintenance, adjusted coloring, flexible arrangements, and in particular they take up less space.
“PLEDs” are based on organic polymers and are perfect for use for flexible films. For example, a new application is the so-called “E-Paper”. PLEDs are normally manufactured with homogeneous catalysis using palladium (“C-C coupling reaction”). Heraeus offers you a wide range of
homogeneous catalysts .
The latest developments for the manufacture of blue emitters for screens are based on organic or organometallic materials (“OLEDs“, “Organic-Light-Emitting Diodes“), e.g. highly sophisticated precious metal complexes of iridium.
Heraeus is your partner for the respective platinum group metals compounds for the manufacture of such emitters.
The increasing miniaturization of electronic components in line with requirements for highest purity levels need innovative solutions for ultra-thin metal layers.
Here, the established sputter technologies are often not precise enough. However, “MOCVD” (“Metal-Organic Chemical Vapor Deposition“) offers decisive advantages: high-purity deposition of metals from the gas phase on a nm scale. In this field the term “ALD” (“Atomic Layer Deposition“) is used, too. Also recently platinum group metals complexes, e.g. Ruthenium, with organic ligands has been applied to MOCVD.
With its outstanding experience in organometallics, Heraeus is your perfect partner for developing and manufacturing tailor-made organometallic complexes for MOCVD applications.
Currently the limited fossil energy resources set top priority on the economical usage of solar energy worldwide. Solar cells on the basis of silicon are already used everywhere, but their yields are not sufficient for all regions of the world.
Solar cells of the 3rd generation are based on deep-colored metal complexes which absorb light energy and so generate electric voltage by using physical-chemical processes. They are called “DSCs“ (“Dye-Sensitized Cells“), or simply “Solar Dyes“. Ruthenium in particular has proven to be very efficient for this application.
Heraeus has been closely watching the development of this technology for a long time and offers precious metal compounds suitable for solar applications.
