Abstract
- We report the first study on in-situ co-growth of biphasic CsPbBr 3 and Zn-Cd-S quantum dots (QDs) in borosilicate glass, and provide explicitly evidence of their morphology and nanoscale distribution. Such biphasic QDs co-doped nano-glass composites show unique green and red dual-band emissions. By changing the thermal heating scheme, the fluorescence intensity ratio (FIR) and thus the apparent color can be widely adjusted. The FIR can be also fine-tuned simply by varying the excitation wavelength. Based on the FIR, a self-calibrated X-rays dosimeter is constructed, which also possesses a good thermal stability. Although the X-rays induced scintillation weakening occurs, it can be readily recovered by post-thermal-annealing. [ABSTRACT FROM AUTHOR]
