“…Promising trichromatic phosphors [26] and alternative light emitters [27] are developed and further promoted by current trends of visible-light communications [28]. Although rare-earth doped epitaxial Y 3 Al 5 O 12 has been successfully grown by PLD [29] and recently phosphor YAG:Ce crystal has been reported [30,31], the high temperatures required for growth is clearly incompatible with our concept. Therefore, the application of polymer-phosphor composites is a unique solution.…”

Pulsed laser deposition on 3-dimensional micro-objects of complex morphology is demonstrated by the paradigmatic growth of cellulose and polymer/Y3Al5O12:Ce phosphor composite nanolayers. Congruent materials transfer is a result of multicomponent ablation performed by relatively low fluence (<200 mJ cm−2) ArF excimer laser pulses (λ = 193 nm). Films grown on optical and engineering components, having a thickness from ~50 nm to more than ~300 nm, are durable, well adherent and maintain the structural and functional properties of the parent solids. The results verify the unique capabilities of deep-ultraviolet pulsed laser deposition of novel functional nanostructures on arbitrary surface morphologies and highlight its potential in future 3-dimensional nanotechnologies.
