“…In recent years, rare-earth (RE) luminescent materials have attracted great attention due to their unique characteristics of up-conversion (UC) and near-infrared (NIR) down-conversion (DC) quantum cutting (QC), which benefits from the rich energy levels and 4f orbital electron transition [1]. They can be widely used in the fields of biological imaging, drug delivery, solid-state multicolor display, temperature sensor, solar cells, and so on [2][3][4][5]. UC process is a nonlinear optical process, which converts low-energy light, usually near-infrared (NIR) or infrared, to higher energies, ultraviolet or visible, via multiple absorptions and energy transfer (ETs) [6][7][8].…”

In this paper, Ho 3? /Yb 3? co-doped Sodium Gadolinium Fluoride (NaGdF 4 ) phosphors were synthesized by a facile and efficient hydrothermal method. The samples were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), energy spectrum (EDS), and photoluminescence (PL). The results of XRD and SEM indicated that the prepared NaGdF 4 samples have the hexagonal structure and good orientation in the case of changing the concentration of Yb 3? . The results of pump power dependence of up-conversion intensity indicated that the energy transfer mechanism from Yb 3? to Ho 3? is a two-photon process. The energy transfer between Ho 3? and Yb 3? under 448 nm excitation was determined by PL spectra and fluorescence lifetimes. All the results proved that the doping of Yb 3? ions can effectively improve the upconversion luminescence of NaGdF 4 phosphors and achieve quantum cutting efficiency of up to 179.8%. Overall, NaGdF 4 :Ho 3? /Yb 3? have potential application in the field of optoelectronic materials.

Perovskite material is a material with chemical formula ABX 3 -type, which exhibits a similar crystal structure of CaTiO 3 . In this material, A and B are metal cations with ionic valences combined to +6, e.g., Li + :Nb 5+ ; Ba 2+ :Ti 4+ ; Sr 2+ :Mn 4+ ; La 3+ :Fe 3+ , and X is an electronegative anion with ionic valence (−2), such as O 2− , S 2− , etc. The properties of a perovskite material strongly depend on the synthesis route of materials. The perovskite materials may be oxides (ABO 3 :CaMnO 3 ), halides (ABX 3 : X = Cl, Br, I), nitrides (ABN 3 :CaMoN 3 ), sulfides (ABS 3 :LaYS 3 ), etc., and they may exist in different forms, such as powders, thin films, etc. There are various routes for the synthesis of several perovskites, such as solid-state synthesis, liquid-state synthesis, gas-state synthesis, etc. In this chapter, we discuss various techniques for the synthesis of oxide perovskites in powder form using solid-, liquid-, and gas-state synthesis methods, and we also present an overview on the other type of perovskite materials. The X-ray diffraction, scanning electron microscopy, and optical techniques are used to study the purity of crystallographic phase, morphology, and photoluminescence properties of the perovskite materials. Some applications of different perovskite materials are also discussed.

“…Semiconductor nanoparticles (NPs) are also widely applied as LDS materials since their optical absorption and emission spectra can be tuned by varying their size and changing doped species. Cd and Zn-related, [20][21][22] carbon-related 23) and perovskite 24,25) NPs were utilized for improving the quantum efficiency of Si cells. These semiconductor NPs were mainly synthesized by the hot-injection method.…”

We investigate effects of several-hundred-micron thick luminescence down-shifting (LDS) films composed of sol-gel glass with Zn-based nanoparticles (NPs) dispersed on characteristics of Si solar cells. Their internal quantum efficiencies (IQEs) are successfully measured by separating contributions of downshifted photons in measuring reflectance for 300-400 nm, wavelengths of incident photons absorbed by the NPs. We find that IQEs for this wavelength range are more enhanced by employing thicker LDS films, i.e., LDS films with higher optical densities. We also discuss relationship among the number density of NPs in LDS films, their optical properties, and IQEs of cells. We observe a discrepancy between measured and calculated IQEs and indicate escape of downshifted photons across sides of LDS films as its possible origin.
