COMPOSITIONS FOR UV SEQUESTRATION AND METHODS OF USE

Embodiments are directed to compositions comprising photoluminescent elements (e.g., quantum dots) that absorb UV radiation and emit longer wavelength non-ultraviolet radiation (luminescent down shifting), effectively sequestering the UV radiation. In certain aspects the photoluminescent elements ar...

Beschreibung
Zusammenfassung:	Embodiments are directed to compositions comprising photoluminescent elements (e.g., quantum dots) that absorb UV radiation and emit longer wavelength non-ultraviolet radiation (luminescent down shifting), effectively sequestering the UV radiation. In certain aspects the photoluminescent elements are dispersed on or in a material. In a further aspect the material is transparent to light. In one respect the photoluminescent elements are dispersed in a transparent film. Selon des modes de réalisation, l'invention porte sur des compositions comprenant des éléments photoluminescents (par ex., des points quantiques) qui absorbent le rayonnement UV et qui émettent un rayonnement non ultraviolet de longueur d'onde supérieure (abaissement luminescent), séquestrant efficacement le rayonnement UV. Selon certains aspects, les éléments photoluminescents sont dispersés sur ou dans un matériau. Selon un autre aspect, le matériau est transparent à la lumière. À un égard, les éléments photoluminescents sont dispersés dans une pellicule transparente.
