“…In this case, VO 3− 4 groups are excited from the ground state, and, when the energy-matching condition is fulfilled, these excited ions serve as a universal sensitizer for RE ions [16]. Er 3 is an active dopant for downconversion as well as IR to visible upconversion emission because of its favorable electronic energy levels with long-lived excited states.…”

This article reports luminescence studies on wet-chemical route prepared YVO 4 :Er 3 ∕Yb 3 microdisc phosphor. The 980 nm laser excited upconversion (UC) emission intensity ratio of green to red bands is found too high to neglect the contribution from the red emission band, which is not observed normally in Er 3 ∕Yb 3 -doped materials. The red emission is also found absent in the downconversion emission under excitation at 316 nm. The variation of UC intensities with external temperature exhibits a well-fashioned pattern, which suggests that the 2 H 11∕2 and 4 S 3∕2 levels of Er 3 ion are thermally coupled. The YVO 4 :Er 3 ∕Yb 3 phosphor has shown outstanding temperature-sensing behavior with maximum sensitivity of 0.0117 K −1 at 400 K. This material is also employed to develop a latent fingerprint in green color. Furthermore, the present phosphor could be useful for solar cell concentrators, drug delivery, and disease therapy applications.

“…YVO 4 is an important host crystal for lanthanide-doped phosphors. It provides a wide band gap (>10 eV) and suitable Y 3+ sites where trivalent rare-earth ions can be easily substituted without additional charge compensation [52,53]. Furthermore, YVO 4 is an efficient UV phosphor in the near-UV region [54].…”

“…Hydro(solvo)thermal synthesis is a typical solution-based approach, which exploits water or a solvent under elevated temperatures and pressures above its critical point to facilitate reaction of the dissolved material/precursor ions and subsequent crystallization [61, 62, 78, 79]. Hydrothermal methods have been shown to be effective in synthesizing β -NaYF 4 based UCNPs with controlled morphologies, including nanosphere [64], nanowires [80], microrod [65], microprim [81], pindle-like microcrystal [82], and octadecahedron [83].…”

Cancer treatment using conventional drug delivery platforms may lead to fatal damage to normal cells. Among various intelligent delivery platforms, photoresponsive delivery platforms are becoming popular, as light can be easily focused and tuned in terms of power intensity, wavelength, and irradiation time, allowing remote and precise control over therapeutic payload release both spatially and temporally. This unprecedented controlled delivery manner is important to improve therapeutic efficacy while minimizing side effects. However, most of the existing photoactive delivery platforms require UV/visible excitation to initiate their function, which involves the issues of phototoxicity and low level of tissue penetration limiting their practical applications in biomedicine. With the advanced optical property of converting near infrared (NIR) excitation to localized UV/visible emission, upconversion nanoparticles (UCNPs) have emerged as a promising photoactive delivery platform that provides practical applications for remote spatially and temporally controlled release of therapeutic payload molecules using low phototoxic and high tissue penetration NIR light as the excitation source. This article reviews the state-of-the-art design, synthesis and therapeutic molecular payload encapsulation strategies of UCNP-based photoactive delivery platforms for cancer therapy. Challenges and promises for engineering of advanced delivery platforms are also highlighted.
