研究目的
To fabricate highly luminescent nanophosphor for revelation of latent fingerprints, lips prints including infiltrating and non-filtrating surfaces and also to develop luminescent ink for anticounterfeiting applications.
研究成果
Eu3+ doped BiOCl nanophosphors synthesized by solution combustion method show potential for applications in WLEDs, forensic science, and anti-counterfeiting due to their luminescent properties and ability to reveal latent fingerprints and create sharp images under UV light.
研究不足
The study focuses on the synthesis and application of BiOCl: Eu3+ nanophosphors but does not explore the scalability of the synthesis method or the long-term stability of the phosphors in practical applications.
1：Experimental Design and Method Selection:
Solution combustion method was employed using Barbituric acid as fuel to synthesize BiOCl: Eu3+ microarchitectures.
2：Sample Selection and Data Sources:
Bismuth nitrate pentahydrate, ammonium chloride, and concentrated nitric acid were used as reactants. Europium nitrate and Barbituric acid were used as dopant and fuel, respectively.
3：List of Experimental Equipment and Materials:
Powder X-ray diffractometer (XRD, Shimadzu 7000), Scanning electron microscopy (SEM, Hitachi table top, Model TM 3000), Jobin Yvon Spectroflourimeter Fluorolog-3 for photoluminescence measurements.
4：Experimental Procedures and Operational Workflow:
The reaction mixture was introduced into a muffle furnace at 400 ± 100C, calcined at 1000oC for 3h.
5：3h. Data Analysis Methods:
5. Data Analysis Methods: Crystallite size was calculated using Scherrer’s equation, and photoluminescence properties were analyzed.
