标题：tb3 , eu3 co-doped cspbbr3 qds glass with highly stable and luminous adjustable for white leds

abstact：herein, we have introduced rare-earth cations tb3 and eu3 into cspbbr3 qds glass by conventional meltquenching. 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
