The basic principle: a luminescent dye is vapor-deposited onto a surface, and then the speed at which it fades under the influence of light is measured.
These greenhouses are outfitted with transparent roof panels embedded with a bright magenta luminescent dye that absorbs light and transfers energy to narrow photovoltaic strips, where electricity is produced.
reported that the highly luminescent dye doped silica nanoparticles synthesized via modified stober method and they have reported the fluorescent nanoparticles can be used for the bioanalysis and bioanalytical experiments [28].
Design (2) represents the ordinary design in which the luminescent dye is dissolved in PMMA nanohybrid layer then coated on a transparent PMMA substrate as previously described.
Moreover, most of the luminescent dye solutions can induce environmental pollution and even operational risk, which are detrimental to human health.
Another possible application consists in encapsulating a luminescent dye in plain or mesoporous silica nanoparticles for optical biolabeling [10-12].
SPR can be a powerful means to enhance the optical properties of commercially available luminescent dyes [14,20].
Firstly, the signal generation in the crossed-fiber junctions is not limited to luminescent dyes. Quantum dots, which typically have broad excitation spectra, narrow emission spectra, high quantum yield, and high photostability, may be employed.
These products include Semicosil 915 HT, a heat-resistant gel for encapsulating power electronic modules; Lumisil 868 S, an encapsulant for LED chips that prevents sedimentation of luminescent dyes; and Lumisil 885, a silicone rubber for producing optical lenses.
Edinburgh University scientists are improving solar photovoltaic cells with luminescent dyes. House windows and office blocks could be covered in a rainbow of colours producing power.

They can additionally serve as carriers for luminescent dyes, which can selectively influence the color of the light emitted by the LED.
