Abstract:This study aims to develop a novel, efficient, and stable red-emitting material using benzoguanamine in which europium (Eu) is doped. We have demonstrated a simple, low-cost, gram-scale manufacturing process via an anneal synthesis method. By changing the Eu-doping concentration from 1 to 20 wt%, we found that the sample containing the Eu-doping concentration of 10 wt% shows the maximum photoluminescence quantum yield (PLQY) peak of 13.7%. Additionally, we confirmed the characteristic luminescence peaks of Eu … Show more
