Codoping Cr³⁺ and Bi³⁺ in Cs₂Ag_0.6Na_0.4InCl₆ double perovskite combines d→d and s→p electronic transitions to develop a single material showing broad near infrared (NIR) and white light emission. The broad NIR peak overlaps with water vibrational overtone absorption at ≈1000 nm, enabling non-invasive food inspection using phosphor converted light emitting diodes (pc-LEDs).
