“…1 shows the XRD pattern of LaMgAl 11 O 19 : 0.02Er 3 þ , 0.05Yb 3 þ phosphor obtained at calcinations temperature 1100 1C, which can be well-assigned to the reported data of LaMgAl 11 O 19 (JCPDS 26-0873) and confirm that the sample is of hexagonal structure with space group P6 3 /mmc [12]. [24][25][26]. Especially, the green emission is strong enough to be seen by naked eyes in LaMgAl 11 O 19 : 0.02Er 3 þ , 0.05Yb 3 þ sample as presented inset in Fig.…”

“…Lin et al [78] and van Veggel et al [79] applied thermal polymerization to prepare oleic acid-stabilized β-NaYF 4 :Yb 3+ ,Er 3+ /PMMA monoliths, respectively. Lin et al [80] also prepared β-NaYF 4 :Yb 3+ ,Er 3+ (Tm 3+ )-PMMA bulk nanocomposites via an in situ radical photopolymerization method. Photopolymerization has advantages over thermal polymerization, including rapid polymerization rate, low polymerization temperature, low energy consumption, and easy process control.…”

Besides various bio-applications such as biomedicine, bioassay, photon dynamic treatment, and drug delivery, UCNPs have also been used in other applications. They can be explored as a NIR absorber in solar cells because they can absorb NIR light which has been wasted in traditional solar cells. They can be used as sensitizer in photocatalysis due to the energy transfer from UCNPs to the quantum dots or organic dyes. They are considered as next generation anti-counterfeiting materials due to their unique optical properties. In this chapter, the recent progress on other applications (besides bio-application) based on UCNPs is reviewed.Keywords Upconversion nanoparticles Á Solar cell Á Photocatalysis Á Anticounterfeiting materials Á NIR absorber Á Light harvesting Á Downconversion luminescence IntroductionAs was discussed in pervious chapters, UCNPs have attracted a great deal of attention from researchers because of their potential for optical manipulation in many fields (such as temperature sensors, bio-imaging agents, bio-analysis agents, and optical trigger for nanocapsules in medical therapy) [1][2][3]. In addition, UCNPs are widely used in light harvesting (for instance in photovoltaic cells and photosynthesis/photocatalytic reactions) and security applications due to their unique optical properties. This chapter will focus on the applications of UCNPs other than their bioapplications and give a brief review on their mechanisms, manipulative methods, and future development.Rui Wang and Fan Zhang contributed together to this chapter.

“…Rare-earth-ion-doped upconversion (UC) materials are attracted due to their wide range of potential applications including solid-state lasers [1], light emitting devices [2], telecommunications [3], sensors [4] and volumetric displays [1,5]. Photon UC is a process in which the sequential absorption of two or more photons leads to the emission of light at shorter wavelength than the excitation wavelength.…”
