Frontispiece: Mesoporous Silica Particles Integrated with All‐Inorganic CsPbBr3 Perovskite Quantum‐Dot Nanocomposites (MP‐PQDs) with High Stability and Wide Color Gamut Used for Backlight Display

Perovskite Quantum Dot LEDs. In their Communication on page 7924 ff., R. S. Liu et al. describe the generation of a white LED device through excitation of a silicone resin containing green mesoporous silica-CsPbBr3 and red CsPb(Br0.4I0.6)3 perovskite quantum dots with a blue InGaN chip.
