## Description

- description: "Different concentrations of Dy3+ and perovskite quantum dots (PQDs)
    were simultaneously embedded in the B\x02Si-Zn glasses by melt-quenching and heat-treatment
    subsequently. A battery of experimental results including TEM, distribution of
    different elements, and photoluminescence prove that partial Dy ions are successfully
    doped into CsPbI3 and played different roles depending on the doping concentration.
    When the Dy3+ concentration is circa 0.1mol%, Dy3+ as a nucleation agent reduces
    the energy required for the precipitation and growth of perovskite quantum dots,
    obtaining outstanding quantum efficiency of 31.82%. The excess Dy3+ supplement
    will prevent the mobility of PQDs elements. Based on the as-made glass sample,
    the remote fluorescent films have been successfully prepared. A kind of prototype
    lighting device was assembled, which demonstrated a high color rendering index
    of 96.5 under the current of 20 mA. Interestingly, by adjusting the concentration
    of Dy3+, color regulation can be achieved from orange-red light to yellow-white
    light. "
