Rare-earth cations like Tb³⁺ emit green light, causing the main peak of bromide lead cesium to exhibit some redshift, owing to the energy transfer between CsPbBr₃ and Tb³⁺. To achieve adjustable light, Eu³⁺ emits red light, which was doped in this glass with different proportions to solve the problem of red deficiency. More importantly, Tb³⁺ and Eu³⁺ co-doped CsPbBr₃ QDs glass shows a series of desirable characteristics due to the energy transfer between Tb³⁺ and Eu³⁺. Interestingly, the blue light radiated by blue chip can excite Tb³⁺, Eu³⁺, and CsPbBr₃ perovskite effectively. We acquired high-performance white light-emitting diodes with color-rendering index, color coordinate transformation, and luminous efficiency of 85.7, 4945 K, and 63.21 lm/W under the current of 20 mA. This acquired Tb³⁺, Eu³⁺ co-doped CsPbBr₃ QDs glass proved the significant feasibility of luminescent materials in solid warm light source.23:T551,Abstract CsPbX 3 ( X = Cl, Br, I) perovskite quantum dots (QDs) represent bright and tunable photoluminescence, it is regrettable that the air instability and poor water resistant properties prevent their application in optoelectronic devices. At the same time, the toxicity of lead is also a major factor restricting its development. As a consequence, we demonstrate the partial replacement of Pb with Mn through conventional melt‐quenching and heat‐treatment method preparation of Mn‐doped CsPb(Cl/Br) 3 QD glass. Mn‐doped CsPb(Cl/Br) 3 QD glass exhibits high luminescent intensity like QDs. It is important that Mn‐doped CsPb(Cl/Br) 3 QD glass with Dual‐Color maintained the same lattice structure like Mn‐doped CsPb(Cl/Br) 3 QDs, and highly homogeneous spectral characteristics of Mn luminescence. The intensity and position of this Mn‐related emission are also tunable by altering the experimental parameters, such as the Pb‐to‐Mn feed ratio, annealing temperature. More importantly, the as‐prepared orange Mn‐doped CsPb(Cl/Br) 3 QD glass was employed to fabricate white LEDs combined with a commercial Ce 3+ :Y 3 Al 5 O 12 phosphor‐in‐glass (Ce‐PiG) on top of a InGaN blue chip. And the constructed WLEDs generate a warm white with an optimal luminous efficacy (LE) of 67.00 lm/W, a high CRI of 81.4, and a low CCT of 4902 K.
