“…In this case, host lattice regulation is one of the most effective strategies to regulate the trap density and distribution. 22,26,49 For instance, Lai et al 50 changed the matrix structure, increased the trap density, and regulated the trap distribution by means of hetero-valence substitution of matrix ion pairs, making it possible to store optical information (Fig. 3(A)).…”

“…Persistent luminescence (PersL) refers to the phenomenon where a material continues to emit light after the excitation source has been removed [1]. PersL is applied in many fields, such as anti-counterfeiting [2,3], information storage [4][5][6][7][8], thermal sensors [9], lighting [10][11][12][13][14][15] and imaging [16][17][18][19]. In terms of imaging, the development of nanoprobes that can emit deep-red or near-infrared (NIR) light has attracted the attention of the scientific community [20][21][22][23][24][25][26].…”

Near-infrared (NIR) persistent luminescence (PersL) materials have demonstrated promising developments for applications in many advanced fields due to their unique optical properties. Both high-temperature solid-state (SS) or hydrothermal (HT) methods can successfully be used to prepare PersL materials. In this work, Zn1.33Ga1.34Sn0.33O4:0.5%Cr3+ (ZGSO:0.5%Cr3+), a newly proposed nanomaterial for bioimaging, was prepared using SS and HT methods. The results show the crystal structure, morphology and optical properties of the samples that were prepared using both methods. Briefly, the crystallite size of the ZGSO:0.5%Cr3+ prepared using the SS method is ~3 µm, and as expected, is larger than materials prepared using the HT method. However, the growth process used in the hydrothermal environment promotes the formation of ZGSO:0.5%Cr3+ with more uniform shapes and smaller sizes (less than 500 nm). Different diameter ranges of nanoparticles were obtained using HT and ball milling (BM) methods (ranging from 25–50 nm) and by using SS and BM methods (25–200 nm) as well. In addition, the SS-prepared microstructure material has stronger PersL than HT-prepared particles before they go through ball milling to create nanomaterials. On the contrary, after BM treatment, ZGSO:0.5%Cr3+ HT and BM NPs present higher PersL and photoluminescence (PL) properties than ZGSO:0.5%Cr3+ SS and BM NPs, even though both kinds of NPs present worse PersL and PL compared to the original particles before BM. To summarize: preparation methods, whether by SS or HT, with additional grinding as a second step, can have a significant impact on the morphological and luminescent features of ZGSO:0.5%Cr3+ PersL materials.
