White-light emission from yttrium iron garnet (YIG)
APL Materials, 2023 Single-phase phosphors that emit broadband white-light are needed for white-light-emitting diodes (wLEDs) to reach their full potential. However, it is challenging to achieve broad white-light emission from single-phase materials.

White Light Emission from Vegetable Extracts [PDF]
Scientific Reports, 2015 AbstractA mixture of extracts from two common vegetables, red pomegranate and turmeric, when photoexcited at 380 nm, produced almost pure white light emission (WLE) with Commission Internationale d’Eclairage (CIE) chromaticity index (0.35, 0.33) in acidic ethanol.

Efficient white-light emission from Zn2GeO4 nanomaterials [PDF]
Oxide-based Materials and Devices X, 2019 Zn_2GeO_4 is a novel transparent conductive oxide material, with an ultra-wide band gap of 4.5 eV, and rather good electrical conductivity. Zn_2GeO_4 nano-and microwires grown by a thermal technique show two intense emission bands centered in the UV and VIS region, respectively.
