A rapid synthetic method for highly photoluminescent (PL) nitrogen-doped carbon quantum
dots (N-CQDs) was developed by using a microreactor with foamy copper having different …

In this review, first, we discussed the effect of phosphor features on optical properties by the
software simulation in detail. A combination of these parameters: phosphor material …

In this paper, to our best knowledge, it is the first time to present a precise simulation and
detailed design of angular correlated color temperature (CCT) distribution of white LEDs …

To enhance the uniformity of correlated color temperature (CCT) and luminous flux, we
integrated ZrO2 nanoparticles into white light-emitting diodes. This novel packaging scheme …

Owing to the strong light scattering effect of TiO 2 nanoparticle and silicone composite, a
method for improving optical performances of chip-on-board (COB) packaging LEDs was …

We present an optical ray-tracing study which investigates the influence of the refractive
indexes of the matrix and the phosphor materials as well as the phosphor particle sizes of …

We demonstrated a conformal phosphor coating method for phosphor-converted white light-
emitting diodes (LEDs) using capillary microchannel formed by a fixture. The mixture of the …

Based on electrospinning technology, in this study, we fabricated poly (lactic-co-glycolic
acid)(PLGA) nanofiber films with high reflectivity and scattering properties. Various films with …

For a systematic approach to improve the white light quality of phosphor converted LEDs
and to fulfil the demands for colour temperature reproducibility and constancy, it is …

We demonstrated a thermal remote phosphor coating method for realizing high angular
color uniformity (ACU) and high efficiency of phosphor-converted white-light-emitting diodes …
