Broadening the Photoluminescence Excitation Spectral Bandwidth of YVO4:Eu3+ Nanoparticles via a Novel Core-Shell and Hybridization Approach

Abstract: For many optoelectronic applications, it is desirable for the lanthanide-doped phosphors to have broad excitation spectrum. The excitation mechanism of the lanthanide-doped YVO4, a high quantum efficient lasing material, primarily originates from the energy transfer process from the host VO43− complexes to the lanthanide ions, which has an excitation spectral bandwidth range of 230–330 nm. For applications in silicon solar cells, such phosphors can convert ultraviolet light to visible light for more efficient … Show more

“…16,17 Generally speaking, the matrix materials for optical temperature measurement include nanorods, nanoparticles, core-shell particles, glass ceramics containing fluorine nanocrystals and oxide blocks. [18][19][20][21][22] This means that the phosphor can be resistant to oxidation and high temperature, and not react in harsh environment and remain stable. Trivalent lanthanide ions and some transition group ions are used as luminescent centers or activators in optical thermometry.…”

“…Huang et al [ 1 ] employed a novel core-shell and inorganic-organic hybridization strategy to fabricate Eu 3+ -doped UVO 4 nanoparticles to broaden their excitation spectral bandwidth to the range of 230-415 nm, thereby covering the entire ultraviolet spectrum of solar light. This feature is useful, given that for optoelectronic applications it is desirable for lanthanide-doped phosphors to have a broad excitation spectrum.…”

“…In fact, while lanthanide-doped YVO 4 (a high quantum efficient lasing material) can be used in silicon solar cells and convert ultraviolet light to visible light for more efficient power generation, its spectral range is not broad enough to cover the entire ultraviolet spectrum of solar light. Herein, Huang et al [ 1 ] solved this issue by broadening the spectral bandwidth of these materials, enabling further applications in silicon solar cells.…”
