Enhancing the temperature sensing property of a Ca0.79−xBixEr0.01Yb0.2MoO4 phosphor via local symmetry distortion and reduction in non-radiative channels

Singh, Sachin; Kachhap, Santosh; Sharma, Manisha; Singh, Sunil Kumar (Royal Society of Chemistry, 2023-05-16)

We demonstrate an enhancement in the upconversion (UC) emission and temperature sensing property of a CaMoO4:Er/Yb phosphor via distortion of the local symmetry environments and reduction in no-radiative channels. Bi3+ ion ...
Impact of crystal structure on optical properties and temperature sensing behavior of NaYF4:Yb3+/Er3+ nanoparticles

Dubey, Charu; Yadav, Anjana; Baloni, Diksha; Kachhap, Santosh; Singh, Sunil Kumar; Singh, Akhilesh Kumar (Royal Society of Chemistry, 2023-07-11)

We report a comprehensive study of the structural, morphological, and optical properties, and UC-based ratiometric temperature sensing behavior of (α) cubic and (β) hexagonal phases of NaYF4:Yb3+/Er3+ nanoparticles. The ...
Lanthanide-doped inorganic halide perovskites (CsPbX3): Novel properties and emerging applications

Kachhap, Santosh; Singh, Sachin; Singh, Akhilesh Kumar; Singh, Sunil Kumar (Royal Society of Chemistry, 2022-02-02)

Inorganic halide perovskites (IHPs) have provoked intense research efforts because of their superior stability, excellent optoelectronic properties, cost-effectiveness, and striking optoelectronic applications. Recently, ...
