Photoluminescence: Applications

Photoluminescence: Applications

Photoluminescence offers a wide range of applications due to its inherent sensitivity and selectivity. This technique allows for both direct and indirect analyses of the analyte. Direct quantitative analysis is possible when the analyte exhibits a favorable quantum yield for fluorescence or phosphorescence. However, an indirect analysis may be feasible if the analyte is not fluorescent or phosphorescent, or if the quantum yield is unfavorable. Indirect methods include reacting the analyte with...

Systematic investigation of varying microlens spacing (100–135 μm).
Ray-tracing simulations based on geometric optics.

Main Results:

Optimal performance achieved with 120 μm microlens spacing.
Increased emission angle from 80° to 120°.
Enhanced luminous efficacy by 12.5%.
Improved scattering ratio from 51.4% to 80.3%.
Increased color conversion efficiency from 64.7% to 74.6%.

Conclusions:

Laser-fabricated MLAs effectively enhance optical performance of PiG structures.
