near 480 nm is significant. This strongly suggests that a complex between pyrene units is also formed in the polymer. The fluorescence spectra of PTMSBDP and PBDP show two distinct bands similar to the ones observed in the fluorescence spectra of DEP . These result[r]

Figure 14 shows the atomic force microscope (AFM) surface images of the thin pentacene film deposited on the interfacial layer. In the device showing high mobility, large and rigid granular domains were observed, for example, in the case of B3PyMPM, B4PyMPM, B2[r]

Bài thuyết trình Giới thiệu về OLED (Organic Light - Emitting Diode) bao gồm những nội dung về công nghệ OLED, thành phần cấu tạo và công đoạn chế tạo 1 tế bào OLED, cơ chế phát sáng của OLED, một số loại OLED và ứng dụng thực tế, ưu và nhược điểm của OLED.

Trong nghiên cứu này, hệ thống twin-layer porous substrate photobioreactor được sử dụng để nuôi cố định H. pluvialis với chiếu sáng bằng Light Emitting Diode (LED) đơn sắc màu đỏ hoặc lam hoặc kết hợp đỏ và lam đồng thời.

1. Introduction
Since the pioneering works on the first double-layer thin-film Organic electroluminescence (EL) devices (OLEDs) by C. W. Tang and co-workers in the Kodak Company in 1987 (Tang 
Vanslyke, 1987), OLEDs have attracted enormous attentions in the scien[r]

This study analyzed the endogenous changes, which were particularly influenced by the spectrum of light emitting diode (LED) with induction flowering time from 30th to 40th day. In the 40th day of the flowering process, when the average number of flower buds get the highest, endogenous carbohydrate[r]

Figure 7 shows that while in solution only a blue-green emission is observed, in the solid
state an additional narrow red-shifted emission at 680 nm is also present in the PL spectrum. This red shifted absorption was peculiar to the solid state and could not be[r]

Organic Light Emitting Diodes have made great progress since their first presentation based on small molecule organic materials by Tang and Van Slyke in 1987. After more than two decades of research, the OLEDs emerged as an important and low-cost way to replace liquid cryst[r]

First, the current flows were observed for sample and reference devices doped with Bu 4 NBF 4 during the electric field treatment under given temperature. Figure 2[r]

The LED fabrication started by thoroughly cleaning the PEDOT:PSS substrate with acetone and iso-propanol under sonication for 3 min. Then, the TFB hole trans- porting solution was spun coated at 1,500 rpm for 30 s, followed by baking for 10 min at 75°C to evaporate the re[r]
