研究目的
Investigating the development of Mn2+‐activated Cs3Cu2I5 yellow‐emitting phosphors for white‐LED applications.
研究成果
The Mn2+‐activated Cs3Cu2I5 halides are promising yellow‐emitting candidates for NUV chip‐based white‐LED, exhibiting excellent thermal stability and suitable optical properties for indoor illumination.
研究不足
The study focuses on the synthesis and characterization of Mn2+‐activated Cs3Cu2I5 halides, with potential limitations in scalability and practical application in commercial white‐LED devices.
1：Experimental Design and Method Selection:
The Mn2+‐activated Cs3Cu2I5 halides were synthesized via the solid‐state reaction technology under a reducing atmosphere (N2:H2 = 95%:5%).
2：Sample Selection and Data Sources:
Starting materials such as CsI, CuI, and MnCl2 were employed according to stoichiometric proportions.
3：List of Experimental Equipment and Materials:
A X‐ray diffractometer (Bruker D8 Advance), a field‐emission scanning electron microscope (FE‐SEM; HITACHI SU3500), and a fluorescence spectrometer (Edinburgh FS5) were used for characterization.
4：Experimental Procedures and Operational Workflow:
The mixtures were ground and sintered in a furnace at 450°C for 6 hours.
5：Data Analysis Methods:
The luminescent behavior and thermal resistance were analyzed using emission spectra and temperature‐dependent measurements.
