Mini Light-Emitting Diode Technology with High Quantum Efficient NIR-II Partially Inverse Spinel MgGa2O4:Cr3+,Ni2+ Nanophosphors
Description
The increasing demand for second near-infrared (NIR-II) region materials, which retain the advantage of minimal scattering and immense applications in the medical and NIR spectroscopy field, has led to considerable research in this region. A mini light-emitting diode (mini-LED) is essential for backlighting liquid crystal displays, indicating the need for the small size of phosphors. However, current market phosphors must be more significant to be a viable option for mini-LEDs. This scenario necessitates the synthesis of small-sized phosphors to be used in mini-LEDs. In this work, a mesoporous silica nanoparticle (MSN) and incorporated the Mg1−yGa2−xO4:xCr3+,yNi2+ system is fabricated. The results showed a steady NIR-II signal at 1270 nm and an enhanced energy transfer with a high quantum yield of 79.2% for a nanophosphor. The mini-LED package revealed a 1000–1600 nm signal, qualifying the nanophosphor for realistic applications. This work can make provisions for various NIR-II nanophosphors in the LED industry.
That dataset provides the raw data of room-temperature excitation and emission spectra and decay profiles, temperature-dependent photoluminescence and decay profiles, and high-pressure-dependent photoluminescence of Mg1−yGa2−xO4:xCr3+,yNi2+.
