## Title

- title: 'Blue Light Excitable Near-Infrared Luminescence Material Yb2−2xCr2xW3O12:
    Cr3+ → Yb3+ Energy Transfer, Mechanisms of Antithermal Quenching, and High-Performance
    pc-LED Applications'

## Description

- description: In this work, a negative thermal expansion (NTE) material Yb2−2xCr2xW3O12
    was prepared. it was concluded that, at room temperature, the sample adopts a
    trihydrate orthorhombic structure and does not exhibit negative thermal expansion
    (NTE) behavior. However, after dehydration at 373 K, anhydrous orthorhombic Yb2W3O12
    (space group Pbcn), which exhibits obvious NTE properties, was obtained. The underlying
    mechanism is that when water molecules enter the crystal and occupy vacancies,
    the Yb−O−W bonds bend, restricting the transverse thermal vibrations of the Yb−O−W
    bonds. The characteristic emission of Yb3+ within the range of 800−1300 nm was
    observed under 468 nm blue light irradiation due to the efficient energy transfer
    from Cr3+ → Yb3+. Remarkably, the prepared NIR phosphor has antithermal quenching
    performance, and at 398 K, the intensity of the strongest emission can maintain
    1.89 times that of the room temperature, surpassing most NIR phosphors. The antithermal
    quenching phenomenon is attributed to cell contraction, which reduces the distance
    between the sensitizer and activator, thereby enhancing the energy transfer efficiency
    and increasing the luminous intensity. The combination of 460 nm excitable strong
    NIR emission and antithermal quenching suggests potential application in biomedical
    imaging and infrared night vision technologies. The NIR pc-LED device, prepared
    by coating the Yb1.94Cr0.06W3O12 phosphor on a commercial 460 nm chip, demonstrated
    a high optoelectronic efficiency and high output power, making it well-suited
    for night vision applications.Furthermore, the efficient NIR-I/II emission from
    Yb1.94Cr0.06W3O12 was proved to be highly effective for compositional analysis.This
    study offers valuable insights for designing NIR phosphors with excellent thermal
    quenching resistance.
