Tuning light emission in Bi and V codoped MgAl2O4 nanostructured films

This study investigates the synthesis of novel Bi and V-codoped MgAl2O4 nanostructured thin films for near-white-light emission upon UV excitation. Sequential pulsed laser deposition (PLD) from Bi, V, and MgAl2O4 targets was employed to prepare nanostructured films with different compositions. The f...

Sequential pulsed laser deposition (PLD) from Bi, V, and MgAl2O4 targets was employed to prepare nanostructured films with different compositions. The films have been thoroughly analyzed using Rutherford backscattering spectrometry (RBS), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and photoluminescence spectroscopy (PL). Upon heat treatments at 500 °C and 800 °C, the films exhibit a broad blue emission in Bi-doped films and a broad yellow emission in V-doped films, respectively. We demonstrate that a strategic combination of Bi and V codoping in MgAl2O4 nanostructures results in near-white light emission. This study highlights the ability to finely control the nanostructure and emission properties of thin films using PLD, and the use of abundant and non-toxic elements to produce white light emission, with significant implications for advanced and sustainable photonic applications.Agencia Española de Investigación (AEI, Ministerio de Ciencia, Innovación y Universidades) y el Fondo Europeo de Desarrollo Regional (FEDER) PID2021-123190OB-I00Consejo Superior de Investigaciones Científicas CSIC PIE-202050E195 y 2021AEP128IOMCIN/AEI/10.13039/501100011033, por el Plan de Recuperación, Transformación y Resiliencia, y por el programa NextGenerationEU/PRTR de la Unión Europea FJC2020-044866-IMinisterio de Ciencia, Innovación y Universidades de España ICTS-2020-02 US-4 (FEDER/UE)ElsevierFísica Atómica, Molecular y NuclearAgencia Estatal de Investigación.
