How do Nanophosphors Differ from Conventional Phosphors?
Nanophosphors are phosphors that have at least one dimension in the nanometer range (1-100 nm). They differ from conventional phosphors in several key ways:
Size-dependent properties: The optical and electronic properties of nanophosphors can be tuned by changing their size, which is not possible with bulk phosphors. Increased surface area: The high surface-to-volume ratio of nanophosphors can enhance their luminescent efficiency. Quantum confinement effects: At the nanoscale, quantum confinement can lead to discrete energy levels, which can result in more efficient light emission.
