Abstract
Here, we present the synthesis of all-inorganic mixed-halide nanocrystals with color-tunable emission (464–667 nm) having narrow emission line-widths (23–47 nm); we synthesize the nanocrystals in an ambient atmosphere by employing a newly reported saponification process in our laboratory. This inert gas-glovebox-free protocol synthesis technique offers simplicity and low cost in the preparation of high-quality nanocrystals. Notably, nanocrystals with different emission wavelengths resulted in tunable correlated-color temperature (2513–9783 K) while maintaining a high color rendering index (up to 95), desirable for white light. Thus, the experimental results suggest that the nanocrystals obtained by the saponification process in this work can be used for future indoor illumination.
