Copper (I) halide-based inorganic–organic hybrid materials as a promising candidate for white light-emitting diode (WLED) application have attracted much attention. However, the poor stability of copper (I) halide-based materials largely limits their development, which is mainly due to the thermal instability and ligand exchange reaction between them. Here, a remote type configuration was adopted to eliminate the thermal threats and a layer by layer technology avoiding direct mixing was used to prevent the ligand exchange. WLEDs with widely variable color temperatures (2919–7736 K) were fabricated by depositing three copper (I) halide-based phosphor layers. Benefiting from the broad full width at half-maximum (FWHM) properties, all the WLEDs exhibit high color rendering index (>90). Besides, The WLEDs possess excellent color stability against the increasing of current.
