While nanophosphors offer numerous advantages, there are several challenges associated with their use:
Synthesis: Producing nanophosphors with consistent size, shape, and composition can be challenging and requires precise control over the synthesis process. Stability: Nanophosphors can be chemically and physically unstable, which can affect their performance over time. Toxicity: Some nanophosphors, especially those containing heavy metals, can be toxic and pose environmental and health risks. Cost: The production of high-quality nanophosphors can be expensive, limiting their widespread adoption.
