An Integrated DFT-FDTD Design of Plasmon-Enhanced Lead-Free $C s S n$ $_{x}$ $G e$ $_{1 - x}$ $I$ $_{3}$ Perovskite LEDs

Shoumik Debnath, Sudipta Saha, Khondokar Zahin +2

CsSn $_{x}$ Ge $_{1 - x}$ I $_{3}$ as lead-free perovskites are promising for next generation NIR emitting perovskite LEDs due to their tunable bandgaps and stability. However, they suffer fr…

Composition-Dependent Plasmon-Enhanced Emission in Lead-Free Cs $_{3}$ Cu $_{2}$ X $_{5}$ Halides: A DFT--FDTD Study

Shoumik Debnath, Sudipta Saha, Khondokar Zahin +2

Lead-free Cs $_{3}$ Cu $_{2}$ X $_{5}$ (X = Cl, Br, I) halides exhibit high photoluminescence quantum yields and excellent ambient stability, yet light-emitting devices based on these materia…
