## Description

- description: 'To call for green and low-carbon lighting development strategy, sunlight-like
    health lighting has become the next generation of light-emitting diode (LED) trends.
    The conventional LEDs are deficient in the violet part and contain high-radiation
    blue light which is harmful to human eyes. The traditional organic phosphor and
    chip packaging mode leads to poor heat dissipation. Therefore, it cannot meet
    the human demand for high-quality, healthy lighting. In this study, a series of
    violet-excitable blue Sr5(PO4)3Cl: Eu2+ (SPOC) phosphor-in-glass (PiG) films were
    prepared. The PiG film can not only compensate for the violet-yellow gap in the
    spectral component but also have excellent luminescence performance and reliability.
    Significantly, the lower co-sintering temperature (335 ℃) allows it to maintain
    89% of the initial phosphor quantum efficiency. Relative to the initial state,
    PiG (Ea = 0.143 eV) at the optimal sintering temperature maintains a 34% higher
    resistance to thermal quenching than phosphor-in-silicon (PiS) at 175°C. This
    blue PiG-prepared color converter was remotely packaged with a violet chip to
    achieve a sunlight-like LED with a color rendering index of 96.3 and 100% color
    saturation. This research offers great potential for the development of next-generation
    sunlight-like health lighting.'
