摘要

Laser-driven projection display puts forward urgent demand for color converter materials to achieve wide-color-gamut and high-quality image presentation. In this study, a hierarchical structure quantum dots-in-glass film (QiGF) is fabricated via co-sintering stable green/red-emitting CsPbX_3@ glass (X_3 = Br_3, Br_(1.5)I_(1.5)) and commercial low-melting glass on the sapphire substrate. Benefiting from the well-retained optical properties of CsPbX_3 quantum dots in amorphous glass and high thermal conductivity, QiGF succeeded in inhibiting luminescence saturation after 20 W mm~(?2) blue laser irradiation. A brand-new white-lighting source designed by coupling a blue laser with a pattern “QiGF wheel” produced ultra-narrow blue/green/red tri-color emissions and total luminous flux of 146 lm. Accordingly, a QiGFconverted laser projection system is successfully designed for the first time, showing more natural and real color restoration for its wide color gamut display feature (157 of conventional light-emitting diode projection and 107 of NTSC standard). The present study highlights the practical application of CsPbX_3 quantum dots composite as an efficient laser-driven color converter in projection display.
