Abstract
We investigated the effect of the partial replacement of Pb2+ with Mg2+ in CsPbX3 (X-halides) on photophysical properties and their potential applications in light-emitting diodes (LEDs). The new composites exhibited a slight variation in the lattice dimension without altering their structure and morphology. However, the replacement of Pb2+ with Mg2+ imparted enhancement in photoluminescence and bandgap energies with maintaining the high luminous property. As a result, the application of these nanocrystals as the color conversion layers (3D printing-based design) in the fabrication of white LEDs generated white light with excellent color characteristics.
