“…The characteristic peak at 721 cm −1 is due to the Eu−Br bond. 32 The peaks at 996, 992, 909, and 721 cm −1 are absent in the CsPbBr 3 FITR spectrum. Therefore, the appearance of these peaks in Eu-doped CsPbBr 3 confirms the presence of Eu in the lattice structure.…”

We report blue emission, along with the characteristic green emission, in CsPbBr 3 nanocrystals (NCs) due to the doping of Eu 2+ ions. The doping of Eu 2+ was confirmed using TEM-EDAX, FTIR, and XPS techniques. The undoped CsPbBr 3 NCs show sharp green emission peaking at 515 nm (fwhm ∼24 nm). Whereas Eu 2+ :CsPbBr 3 NCs show two emission peaks at 498 and 442 nm with fwhm ∼20 and ∼13 nm, respectively. A shift in the green emission of doped NCs is because of reduced average particle size from 19 to 7 nm. The additional emission peak at 442 nm is assigned due to the 4f 6 ( 7 F J )5d 1 → 4f 7 transition of Eu 2+ ions. The intensities of blue and green emissions are both significantly influenced by changing the excitation wavelengths. The decay dynamics study suggests an energy transfer from CsPbBr 3 to the Eu 2+ ions. It is also inferred that Eu 2+ doping improves the radiative channels. Further, the CIE coordinate analysis depicts virtuous luminous efficacy of the optical radiation and significant color purity (>85%) of the emission spectra under different excitations. These optical studies show that the Eu 2+ :CsPbBr 3 NCs can be a potential candidate for multicolor LEDs, displays, and anticounterfeiting applications.

“…Europium is a rare earth element which can be used for providing strong emission of red light, with biocompatibility and luminescent properties for biomedical imaging. [253][254][255] The effect of temperature on the luminescent properties of particles was observed through changes in shape and emission intensity. The luminescence intensity decreased with increase in temperature (ie, with measurements in 20-70 °C range) due to non-radiative transition and luminescent quenching.…”

Theranostic agents are promising due to their ability to diagnose, treat and monitor different types of cancer using a variety of imaging modalities. The advantage specifically of nanoparticles is that they can accumulate easily at the tumor site due to the large gaps in blood vessels near tumors. Such high concentration of theranostic agents at the target site can lead to enhancement in both imaging and therapy. This article provides an overview of nanoparticles that have been used for cancer theranostics, and the different imaging, treatment options and signaling pathways that are important when using nanoparticles for cancer theranostics. In particular, nanoparticles made of metal elements are emphasized due to their wide applications in cancer theranostics. One important aspect discussed is the ability to combine different types of metals in one nanoplatform for use as multimodal imaging and therapeutic agents for cancer.
