“…The average crystallite size of the synthesized host was determined using the Scherrer equation (eqn (1)). 26,27 This calculation was based on the peak position and full width at the half maximum of the major peaks obtained from the XRPD data. The calculated crystallite size for the host and Eu 3+ -doped samples was found to vary from 64 to 116 nm with slight variations, as given in Table 1.…”

Rare‐earth (RE)‐activated inorganic nanophosphors have garnered significant attention due to their unique optical properties and versatile applications in fields ranging from lighting and displays to biomedical imaging. The mini review provides a concise overview of recent advances in the synthesis strategies employed for the fabrication of these nanomaterials. Various synthesis techniques, including solid‐state, sol‐gel, solution combustion, hydrothermal, co‐precipitation, and microwave methods have been discussed, highlighting their advantages and limitations in tailoring the properties of nanophosphors. Furthermore, the role of different rare earth dopants and host matrices in controlling the luminescent properties of nanophosphors has been explored. Future perspectives and emerging trends in preparation of RE‐activated inorganic nanophosphors has also been discussed, with an emphasis on addressing current challenges and exploring new avenues for the fabrication of adequate and functional nanomaterials.

The GdAl3(BO3)4:xPr3+ (0 ≤ x ≤ 5.0 mol%) phosphors were prepared through solid state reaction route and characterized for various lighting applications. Powder X‐ray diffraction investigations revel rhombohedral structure matched to JCPDS card no. 83‐1907. The morphological studies confirm the agglomeration of particles with different size and shape. The emission spectra show various emission transitions originating from Pr3+:(3P1,0, 1D2) emission states to their lower lying energy states upon 274 nm NUV excitation with a red shift for x > 0.5 mol%. The colour perception analysis results an intense red luminescence due to efficient energy transfer from Gd3+ to Pr3+ ions. The temperature‐dependent luminescence investigations show good thermal stability even beyond 150°C with an activation energy of 0.24 eV. The observed experimental results show the potentiality of GdAl3(BO3)4:0.5 Pr3+ phosphor for red emitting devices and red component in phosphor converted white LEDs.
