Abstract
- Transition metal ion and/or rare earth ion doped CsPbCl<subscript>3</subscript> nanocrystals (NCs) have attracted extensive attention due to their high combined emission efficiency characteristics. Their high-throughput preparation is of great significance for future industrialization that is still a challenge based on existing batch reaction technologies. Herein, we demonstrate a high-throughput preparation method of Mn<superscript>2+</superscript>-doped CsPbCl<subscript>3</subscript> NCs based on a fluidic channel reactor. The as-prepared NCs show vivid yellowish-orange emission at 600 nm and high photoluminescence quantum yield (PLQY) of 63.3%. Meaningfully, due to the closer bond between surface ligands and NCs, NCs prepared by this method show better water durability than NCs obtained using the traditional hot injection method. Finally, a WLED with a high color rendering index (CRI) of 94 and a low correlated color temperature (CCT) of 3626 K was fabricated by combining the as-prepared yellowish-orange Mn-doped CsPbCl<subscript>3</subscript> with the BaMgAl<subscript>10</subscript>O<subscript>17</subscript>:Eu<superscript>2+</superscript> (BAM:Eu<superscript>2+</superscript>) blue phosphor and CaAlSiN<subscript>3</subscript>:Eu<superscript>2+</superscript> (CASN:Eu<superscript>2+</superscript>) red phosphor on a 375 nm ultraviolet chip. These findings suggest that the Mn-doped CsPbCl<subscript>3</subscript> prepared by the fluidic channel reaction is suitable for WLEDs. Our work paves the way for achieving a continuous, large-scale preparation of perovskite NCs by a fluidic channel reaction for the development of their WLED solid state lighting applications.
