Embodiment Construction

[0064] figure 1 A schematic front view of an embodiment of a light emitting photonic structure generally indicated by numeral 10 is shown. The luminescent photonic structure 10 comprises a luminescent material 14 which, when excited by excitation light 11 having a wavelength within the excitation wavelength spectrum of the luminescent material, emits luminescent light with a luminescent wavelength spectrum. The light-emitting photonic structure 10 has a photonic crystal 14 arranged between two other photonic crystals 12 , 16 . Photonic crystal 14 has a photonic lattice period within the emission wavelength spectrum. The other photonic crystals 12 , 16 have photonic lattice periods within the excitation wavelength spectrum for reflecting excitation light propagating within the photonic crystal 14 .

[0065] Photonic crystal 14 contains a plurality of luminescent centers. The two other photonic crystals 12, 16 also contain luminescent centers, although this is not necessaril...

Abstract

Disclosed herein is a luminescent photonic structure (10). The luminescent photonic structure (10) comprises a luminescent material (14) that when excited by an excitation light (11) having a wavelength within an excitation wavelength spectrum of the luminescent material (14) emits luminescent light having a luminescence wavelength spectrum. The luminescent photonic structure (10) comprises a photonic crystal (14) disposed between two other photonic crystals (12,16). The photonic crystal (14) has a photonic lattice period within one of the luminescence wavelength spectrum and the excitation wavelength spectrum. The two other photonic crystals (12,16) each have a photonic lattice period within the other of the luminescence wavelength spectrum and the excitation wavelength spectrum for reflecting one of excitation light and luminescent light propagating within the photonic crystal (12). Also disclosed herein is a method for fabricating a luminescent photonic structure, and a method for sensing a chemical substance.

Description

technical field [0001] The present disclosure generally relates to a light-emitting photonic structure, a method of fabricating a light-emitting photonic structure, and a method of sensing chemicals. Background technique [0002] Signal strength and signal-to-noise ratio in general can be important considerations for molecular and nanoparticle luminescent technologies, with applications including but not limited to chemical sensing, biochemical sensing, disease diagnostics, and environmental monitoring. [0003] Novel photonic structures with novel properties can be applied in light-emitting devices and optoelectronics. For example, while light-emitting diodes (LEDs) and related solid-state light sources may preferably be preferred over incandescent and fluorescent light, it can be difficult to engineer efficient LEDs with the wavelength spectrum required for an application. Currently, phosphors are used to convert the individual emission colors of LEDs to another color or ...
