Abstract The attainment of white emission from a light-emitting electrochemical cell (LEC) is important. since it enables illumination and facile color conversion from devices that can be cost-efficient and sustainable. However. a drawback with current white LECs is that they either employ non-sustainable metals as an emitter constituent or are intrinsically efficiency limited by that... https://danddcollectiblers.shop/product-category/bath-and-body/
