Rice Husk-derived Biomass Silicon for Single-phase White-light Inorganic Phosphor and WLEDs
A silicate inorganic phosphor matrix, CJU-1-Eu (K3EuSi6O15), based on rice husk-derived biomass silicon, was synthesized via a hydrothermal method. The material was doped with Tb3+ ions, and the effect of Tb3+ concentration was investigated, resulting in a series of tunable white-light inorganic phosphors (CJU-1-Eu:xTb3+) ranging from warm white to cool white. The CJU-1-Eu:0.04Tb3+ inorganic white-light phosphor was combined with a UV chip to produce the white-light-emitting diode (WLED) device. The device exhibited CIE coordinates of (0.332, 0.327) and the color rendering index (CRI) of 86.5 at 100 mA current. This white-light phosphor achieves both the recycling and high-value utilization of rice husk ash.
