研究目的
Investigating the structural and luminescent properties of Holmium doped Lithium Lead Borate glasses prepared by melt quenching technique.
研究成果
The study concluded that the glass structure consists mainly of BO3 and BO4 structural units. A blue emission was observed at 0.5 mol% of Ho3+ ions, indicating potential applications in LED technologies.
研究不足
The study is limited to the analysis of Holmium doped Lithium Lead Borate glasses prepared by melt quenching technique. The luminescent properties were only studied under excitation at 451nm.
1：Experimental Design and Method Selection:
The study involved preparing Holmium doped Lithium Lead Borate glasses using conventional melt quenching technique. Fourier transform infrared (FTIR) and Photoluminescence techniques were employed to study the glass network and luminescent properties.
2：Sample Selection and Data Sources:
Glass compositions were 60B2O3-30PbO-(10-x) Li2O-xHo2O3 (where x=0, 0.1, 0.3 and 0.5 mole%, named as HB, HB1, HB3 and HB5 respectively).
3：1, 3 and 5 mole%, named as HB, HB1, HB3 and HB5 respectively).
List of Experimental Equipment and Materials:
3. List of Experimental Equipment and Materials: Electrical balance, agate mortar and pestle, porcelain crucibles, electric furnace, Thermo Nicolet Avata 370 instruments for FTIR, Horiba Fluorolog spectrofluorometer for Photoluminescence.
4：Experimental Procedures and Operational Workflow:
The batches were melted at 9500C for about 3-4 hours and quenched between two smooth surfaced brass blocks to obtain glass samples. FTIR spectra were recorded in the range of 400 to 4000 cm-1. Photoluminescence spectra were recorded with 450W xexon lamp as a source.
5：Photoluminescence spectra were recorded with 450W xexon lamp as a source.
Data Analysis Methods:
5. Data Analysis Methods: The data was analyzed to identify the structural units in the glass network and the luminescent properties.
