Seaborough Research Explores New Opportunities for Optical Down-Conversion Materials

Ahead of his participation at the 2018 Phosphor Global Summit, we reached out to Dr. Mike Krames, Senior Advisor to Seaborough Research BV, to discuss current challenges and emerging opportunities within the industry. As a 20-year veteran in the compound semiconductor industry, in both start up and large research and development organizations, Mike is a recognized world authority on visible-spectrum LEDs and their applications for lighting and displays.

Why attend this event? 

PGS/QDF is an internationally recognized forum for focused discussion on optical down-conversion technologies, which are critical for many lighting and display applications.

What presentations are you most looking forward to? 

Presentations by the large OEMs are always interesting - to hear how they see the market developing.

What makes the Phosphor Global Summit (PGS) different from other conferences you have attended? 

PGS/QDF is a very focused conference, specifically on optical down-conversion technologies, that allows the speakers and audience to delve deeply into the technology, which is otherwise sometimes skipped over at typical conferences on lighting and displays.

Why is this meeting important to the Phosphor Industry? 

PGS brings together key thought leaders from the development/synthesis side, as well as the applications side, in an interactive, workshop-style setting. It is a very good opportunity for each to share ideas, learn from each other, and advance the field.

What value does the co-location of QDF with the Phosphor Global Summit offer to delegates? 

There is considerable overlap, certainly in the application space, in both phosphor and quantum dot technology. I believe each field benefits from comparing/contrasting itself to the other.

What are some of the industry challenges that this year’s conference will address? 

An emerging area of opportunity is optical down-conversion materials for high brightness applications.  We already see, for example, that incumbent red emitters do not perform well at high photo-fluence and high temperature conditions.  This is already a problem for LEDs, and much much worse for laser diodes. An interesting pre-conference workshop has been put in place that specifically probes these issues.

The title of your talk is “Advancing Down-Conversion Emitters For Solid State Device Applications” why is this topic important to the Phosphor Industry? 

Advancements will harness the power of ion emitters, like Eu3+, for solid state devices for the first time.  Such capability will offer breakthrough performance and new applications, for LEDs, and possibly lasers.
