Bringing heat into the bright side in bio-hybrid LEDs – Heat-BLED

Project description

Phosphor materials that resist heat generation

Commercially available light-emitting diodes rely on phosphor materials doped with materials that are costly and in short supply. A new class of phosphor materials (organic) described as hybrid shows great promise as a more cost-effective and abundant alternative. The main goal of the EU-funded Heat-BLED project is to develop new hybrid phosphor materials that can withstand high photon flux excitations without generating heat or smartly leverage it in dual functional devices (which convert and store energy). Heat-BLED will provide experimental insight into the interaction of protein matrices with light and a profound experimental basis to determine the optimum composition of the matrix to reduce heat generation.

Objective

The main objective of Heat-BLED is the development of new biophosphors able to either stand high photon flux excitations without generating heat or to smartly use the heat in dual functional devices. Heat-BLED will provide experimental insight into the interaction of polymer-fluorescence protein matrix with light and most importantly, provide a solid experimental basis to determine optimum composition of the matrix to effectively reduce heat generation. This will be accomplished by establishing a protocol to quantify the dielectric loss heating under device operating conditions. Moreover, the second approach will be applied to design an innovative family of color down-converting coatings for Bio-hybrid light emitting diodes (Bio-HLED) that repurposes the heat generated under operando conditions. To this end, two strategies will be used. Firstly, the fluorescent protein will be covalently linked to a nanothermometer. Second, a multi-layered biophosphor coating will be fabricated using a transparent thermoelectric generator to convert heat into an electricity.
