## Description

- description: Cr3+-activated near-infrared emitting phosphor has a potential application
    in plant growth and sensing technologies. Herein, we synthesized near-infrared
    emitting La11x/3Al11x1yTixO3:yCr3+ phosphor by a solid-state reaction. La11x/3Al11x1yTixO3:yCr3+
    (x = 0.2, y = 0.003) showed the near-infrared emission at 751 nm with a full width
    at half-maximum of 41 nm under 351 nm excitation. The internal and external quantum
    efficiencies were 54.4 and 25.5 %, respectively. The luminescence intensities
    at 150 °C of the La11x/3Al11x1yTixO3:yCr3+ (x = 0.1, 0.2, and 0.3, y = 0.003)
    were 32, 17, and 3 % of those at room temperature, respectively. The thermal quenching
    effect strongly occurred with increasing the amount of Ti and it was related to
    the change in the absorbance edge of the host material La11x/3Al11x1yTixO3.
