研究目的
Investigating the optical temperature sensing properties of KLa(MoO4)2:Yb3+/Er3+ phosphor through the fluorescence intensity ratio (FIR) method.
研究成果
The KLa(MoO4)2:Yb3+/Er3+ phosphor exhibits excellent optical temperature sensing properties with a maximum sensitivity of 0.0105 K-1, making it a promising material for optical temperature sensors.
研究不足
The study is limited to the temperature range of 303–423 K and does not explore the phosphor's performance at higher or lower temperatures.
1:Experimental Design and Method Selection:
The study involved synthesizing KLa(MoO4)2:Yb3+/Er3+ phosphor via a hydrothermal method and analyzing its upconversion luminescence properties under 980 nm excitation.
2:Sample Selection and Data Sources:
Samples were prepared with varying concentrations of Yb3+ and Er3+ ions.
3:List of Experimental Equipment and Materials:
A Rigaku D/Max-2500 X-Ray diffractometer, FE-SEM (JEOL JEM-6700F), and a Zolix Omni-λ500 spectrograph were used.
4:Experimental Procedures and Operational Workflow:
The phosphor was excited by a 980 nm laser, and temperature-dependent UC spectra were measured from 303 to 423 K.
5:Data Analysis Methods:
The FIR of the green emissions was analyzed using Boltzmann-type distribution law.
