Abstract

2001 nanotechnology nanotechnology V 1505 -254Room-Temperature Ultraviolet Nanowire Nanolasers.-(0001)oriented ZnO nanowires are grown on sapphire substrates by a simple vapor transport and condensation process using Au thin films as catalysts. These nanowires form natural laser cavities with diameters varying from 20 to 150 nm and lengths up to 10 µm. Under optical excitation, surface-emitting lasing action is observed at 385 nm, with an emission linewidth less than 0.3 nm. The chemical flexibility and the one-dimensionality of the nanowires make them ideal miniaturized laser light sources. These short-wave-length nanolasers could have many applications, including optical computing, information storage, and

Enhanced output voltage generation via ZnO nanowires (50 nm): Effect of diameter thinning on voltage enhancement

“…ZnO nanostructures also exhibit robust properties which make them promising candidate to be used in mechanicalelectrical energy conversion devices [11]. ZnO, due to its semiconducting and piezoelectric properties, it is considered highly favorable in UV lasering [12], UV sensors [13], light emitting diodes [14], gas sensors [15,16] and solar cells [17].…”

Влияние пространственной ориентации наностержней ZnO на спектр люминесценции

“…Будучи оптически прозрач-ным в видимом и ближнем УФ диапазонах и благодаря хорошей проводимости ZnO используется для производ-ства компонентов полупроводниковых приборов, датчи-ков, УФ фильтров, в дисплеях и солнечных элементах в качестве прозрачного проводящего электрода [2]. Кроме этого, ZnO является высокоэффективным источником излучения УФ диапазона, его одномерные структуры (наностержни и нанопроволоки) позволяют получить лазерную генерацию [3], тонкие пленки считаются пер-спективным материалом для создания фотодиодов [1].…”

Ultrasound mediated synthesis of CuS nanocrystallites

“…This reveals that the band gap of nanoparticles can be manipulated with the size to adjust desired optical properties, which have drawn attention of researchers working on nanoparticles in the field of nanotechnology. In current years, researchers have given more attention to the preparation of nanoparticles for the applications in a number of fields, such as light emitting diodes and devices [1,2], room temperature field-effect transistors (FETs) [3], quantum dot/wire lasers [3,4], biological imaging [5][6][7][8], sensors [9,10], solar cells [11][12][13], photocatalysts [14,15]. Another wide range of applications of nanoparticles is due to their size dependent optoelectronic properties [16,17].…”
