Special Issue Information

Dear Colleagues,

Photoluminescence nanomaterials, including organic-based, inorganic-based, and organic–inorganic hybrid types, have experienced rapid development in recent years. Great progress in advanced photoluminescence materials has been achieved owing to the controllable synthesis of nanomaterials. New mechanisms and phenomena of photoluminescence nanomaterials that are different from bulk ones are raised and explored. Emerging nanomaterials and quantum dots provide new types of materials for a wide range of applications. Apart from conventional solid-state lighting and display, advanced photoluminescence nanomaterials enable potential applications in biological imaging, sensing, and detection, micro/nanolasers, etc. with high quantum yield and good stability. This Special Issue titled “Advanced Photoluminescence Nanomaterials and Applications” aims to summarize the recent progress and prospects of this field. All types of related papers, including research articles, letters, communications, reviews, prospects, news, and views, are welcome. We sincerely invite you to submit a manuscript for consideration and possible publication in this Special Issue.

The multifunctional platform response to the tumor microenvironment (TME) is critical for the high-precision diagnosis and treatment of cancer with low systemic toxicity. In this regard, vanadium-doped carbon dots (V−CDs) have been developed for TME-activated fluorescence imaging and chemodynamic therapy (CDT). Due to the Forster resonance energy transfer caused by the doped vanadium, the obtained V−CDs displayed quenched fluorescence. Once entering the tumor, the fluorescence imaging ability of the V−CDs are stimulated by the reaction between vanadium and overexpressed H2O2 in a weak acid TME. Meanwhile, the hydroxyl radicals generated by the catalytic reaction of V−CDs could induce oxidative damage in tumor cells for CDT, while showing less cytotoxicity and side effects in normal cells. Therefore, the well-designed V−CDs could be used for TME-activated fluorescence imaging and CDT while maintaining an “inactive” status in normal tissues to ensure low biological toxicity, satisfying the clinical requirements for accurate diagnosis and efficient treatment with low side effects for tumors. Our research provides an effective strategy for designing and preparing multifunctional nanotheranostic drugs responsive to TME for accurate tumor imaging and treatment. Full article

Titanium dioxide nanoparticles play a crucial role in the production of hydrogen gas evolution. Among the four polymorphic phases of TiO2 (anatase, rutile, brookite, and TiO2 (B)), the anatase phase shows good photo activity in catalytic applications. We prepared a single anatasephase of TiO2 nanoparticles usinga facile one-step ionothermal method with the existence of 1-(3,6-dioxa heptane) 3-methyl imidazolium methane sulfonate IL[DOMIMS]. The ionic liquid-based substitution reaction mechanism was utilized for the ionothermal synthesis of TiO2. The anatase phase structure and nanoparticle-like morphology of synthesized TiO2 nanomaterial were confirmed by XRD analysis and TEM studies. The vibrational frequency of the Ti–O–Ti bond at 544 cm−1 was measured usingthe FTIR spectrum, and the UV absorbance of the sample was studied usingthe UV/visible spectra. The prepared TiO2 nanoparticles showed the best results of H2 generation via awater-splitting reaction, liberating 2084 μmol·g−1·h−1 of H2 gas. TiO2 nanoparticles act as a good material for electrochemical applications such as supercapacitors and sensing of dopamine, as well as a better photocatalyst for the degradation of methylene blue.
