Understanding the key parameters necessary for generating uniform Er,Yb co-activated NaYF possessing various selected phases (i.e. cubic or hexagonal) represents an important chemical strategy towards tailoring optical behavior in these systems.

Microglia represent the first line of defense in the central nervous system (CNS) during severe injury or disease such as Parkinson's and Alzheimer's disease as illustrative examples. Hence, to analyze the potential cytotoxic effect of nanorhombohedra exposure in the presence of microglia, we have synthesized Rhodamine B (RhB) labeled-α-FeO N-Rhomb, with lengths of 47 ± 10 nm and widths of 35 ± 8 nm.

- - Researchers developed new semiconducting heterostructures by attaching cadmium selenide (CdSe) quantum dots to porous, rare-earth-doped alkaline earth titanate microspheres (specifically Eu and Pr doped CaTiO3) using advanced synthetic techniques.
- - Optical tests revealed that the charge transfer behavior in these structures varied based on factors like dopant type, reaction temperature, and particle size, with 2.7 nm CdSe QDs combined with CaTiO3 spheres showing significant photoluminescence (PL) emissions.
- - Among the tested materials, CaTiO3 proved to be the best host for the QDs, with notable results showing effective charge transfer, evidenced by a
