Abstract The urgent demand for color conversion composites in laser‐driven projection display technology has highlighted fluorescent phosphor‐in‐glass films (PiGF) as a promising material. newly designed borogermanate glass matrix is proven to be versatile platform incorporating various commercial phosphors create multicolor PiGFs. Notably, the controlled interfacial interaction leads exceptional luminescent performance, particularly achieving unprecedented quantum efficiency rare earth ions activated (oxy)nitrides, which are of critical importance. By conducting comparative analyses static and rotating excitation modes, combined effects thermal quenching intensity on luminescence saturation under high‐power blue laser irradiation explored. developed phosphor wheel, featuring an intricate pattern structure, delivers high‐brightness high‐quality white light with luminous flux (LF) 1665 lm @26.8W mm −2 , efficacy (LE) 84.4 W −1 rendering index (CRI) 92. Introducing four‐color “polygon scheme” significantly expands gamut displays 114% NTSC, thereby enhancing visual experience superior reproduction.

Abstract Owing to the extensive use of lithium compounds in various strategic emerging fields, global demand for minerals has surged recent years. However, existing spectroscopic techniques tend be time‐consuming and inefficient. As a result, there is an urgent need development efficient rapid methods identifying ores. Here, by choosing environment‐friendly Fe 3+ ions as activators ZnAl 2 O 4 (ZAO) spinel oxide host, novel Li + ‐sensitive materials Zn 1‐ x Al :Fe (ZLAO:Fe ) near‐infrared (NIR) phosphors are synthesized. The oxygen vacancy defect levels reduced due occupation interstitial sites , thus prohibiting detrimental electron trapping. Meanwhile, site preference valence state altered doping, resulting more utilization excited electrons octahedral radiative transitions. Notably, optimal ZLAO:Fe ( = 0.4) phosphor presents 53‐fold higher NIR emission intensity than that ZAO:Fe outstanding thermal stability (86%@373 K, 74%@423 K). ceramic plates sensitive additional fabricated their application bearing ores demonstrated. proposed strategy initiates new way design ‐activated multifunctional applications.

Abstract Next‐generation high‐luminance laser lighting faces a crucial challenge in developing transmissive color converter with efficient heat dissipation and phosphor conversion. Herein, unique architecture of Al 2 O 3 particles gradient doping phosphor‐in‐glass film (PiGF) coated on transparent sapphire (AGD‐PiGF@S) is designed prepared by simple multilayer printing low‐temperature sintering strategy.
