The challenge of energy conversion and enhancement has been a problem in the world of lighting technologies as the population and global industrialization grow rapidly. Solid-state lighting (SSL) has proven to be a better alternative in the illumination industry because of its environmentally friendly and high energy efficiency. Lanthanide-doped phosphors have gained global attention in SSL because they have versatile applications with enhanced overall performance and luminescence. This review delves into the advancement in lanthanide-doped phosphors for Solid-state lighting (SSL) applications. It discusses the in-depth analysis of how to tailor the crystal lattice design, optimize the host material for emission efficiency, and minimize the non-radiative pathways. This paper further discusses the lanthanide-doped phosphor composition, strategies to obtain desired emission spectra, and enhanced color rendering index with the Energy transfer mechanism and the synthesis techniques. This review also addresses 3 processes for expanding the light spectrum, current challenges, future directions, and emerging trends present in the lanthanide-doped phosphor in Solid-state lighting (SSL) applications.

NaY(WO4)2:Eu3+ phosphors were synthesized using high-temperature solid state method. The effects of Eu3+ doping concentrations on structure and photoluminescence properties of the powders were investigated. The results indicate that the pure NaY(WO4)2:Eu3+ phase can be produced by calcining at 800?C where Eu3+ doping does not alter the main phase structure. Eu3+ ions were successfully incorporated into the crystal lattice, replacing Y3+ at the B-site. This caused gradual shifts of the characteristic X-ray diffraction peaks to lower 2? angles. Morphological characterization revealed that the sample particles had irregular polygonal shapes with sizes ranging from 100 to 300 nm. There was minimal variation in morphology among samples with different doping concentrations. The samples exhibited the characteristic spectral emission of Eu3+ and emitted red light at a wavelength of 616 nm when excited by 394 nm near-ultraviolet light. The luminescence intensity of the nanophosphor gradually increased with increasing Eu3+ doping concentration, reaching its maximum at a doping ratio of 0.6, followed by a decrease due to the concentration quenching. The quenching mechanism was analysed to be primarily dipole-dipole interaction, in accordance with the Dexter?s theory of doping concentration. The luminescence positions of the phosphors slightly changed with varying Eu3+ doping concentrations, and the colour coordinates closely matched the standard value of the red colour in the National Television Standards Committee, confirming the stability of the obtained powders as red phosphors.
