摘要：

Domestic lighting using white light-emitting diodes (WLEDs) requires a choice of materials to be eco-friendly as well as economically viable. Revisiting the optical properties of sulforhodamine B (SRB) with a new focus - designing rare-earth-free phosphors - is found here to be highly promising. Relying on a Layered Double Hydroxide (LDH) host, the dye molecules are stabilized, and the inorganic-organic assembly formed is dispersed into silicone. Homogeneous composite films present suitable and stable photometric parameters, making them appropriate candidates to replace red-emitting phosphors based on rare-earth elements.
