The exploitation and utilization of resources in marine environments have ignited a demand for advanced illumination optical communication technologies. Light-emitting diodes (LEDs), heralded as "green lighting sources", offer compelling solution to the technical challenges exploration due their inherent advantages. Among myriad LED technologies, phosphor-converted light-emitting (pc-LEDs) emerged frontrunners applications. At heart pc-LEDs lie phosphor materials, colour-converters that orchestrate emission light. In environment, blue-green light with wavelength 440-570 nm exhibits deepest penetration depth, while other wavelengths are rapidly attenuated shallow layer. Additionally, specific crucial particular However, moist environment well continuous stable pose formidable challenge environmental stability phosphors. Therefore, developing phosphors exceptional colour purity high thermal moisture is paramount Herein, this review delves into application pc-LED technology underwater fishery, exploring development strategies tailored environment. insights presented serve valuable reference further research on devices.

White light-emitting diodes (LEDs) are a new generation of light sources that used in solid-state lighting and information display devices. They generate less thermal radiation than incandescent fluorescent lamps. Phosphor light-emiting (PC-LEDs), which based on this technology, have high luminous efficiency energy efficiency; they compact havу long service life. LED materials subject to such requirements asenvironmental friendliness, transparency the source excitation process, color rendering efficiency. For use LEDs, it is necessary investigate optical properties inorganic doped not only with rare earth elements (due their cost) but also transition metal ions as Mn2+. This review summarizes analyses synthesis, structure, photoluminescent borates MMeBO3, where M = Li, Na, K; Me Mg, Ca, Sr, Ba, Zn Mn2+ Bi3+ co-doped metals (Ce3+, Eu3+). Impurity activators, when introduced into compound's lattice, become main luminescent centers phosphors. Processes transfer from sensitizer activator mechanisms discussed. The dependence size morphology particles materials' luminescence possibility using matrices for phosphors emitting red shown, along tunable white LEDs autoemission displays.
