The main goal of my research is to understand the fundamental principles governing the coexistence of and interactions between different properties in low-dimensional materials, which are often considered to be mutually exclusive. Simultaneous control and manipulation of multiple functionally-relevant properties at the nanoscale could lead to radically new approaches to energy-efficient information technologies, solid-state lighting, photonics, and catalysis. This proposal specifically addresses the importance of multifunctionality for new sustainable technologies with long-term benefits to Canada. My research program is interdisciplinary in nature and uses a combination of synthetic, spectroscopic, structural, physical, and theoretical methods. Within the designed projects we study the role of nanostructure size, composition, phase transformation, native defects formation, and molecular functionalization in enhancing the inherent degrees of freedom at the nanoscale. These projects and the future activities related to the proposal can be classified in two major directions: ******* Energy-Efficient Solid State Lighting and Photonic Technologies. Expanding on my work on functional defect formation and interaction in transparent metal oxide nanocrystals, the goal of this part of my research program is to explore different ways of expanding and manipulating the electronic structure and optical properties of native defect states. As a notable example, we prepared a new class of colloidal hybrid organic-inorganic quasi-single white light emitting nanostructures (NanoLite), which has paved the way to a new approach to solid-state lighting without the need for strategically important rare earth elements. ******* Energy-Efficient Information Technologies. The goal of this set of projects is to investigate the correlations between electrical, magnetic, and optical properties of nanomaterials for energy-efficient and non-volatile information processing, transmittal and storage. The systems of interest include magnetic semiconductor, emerging oxide plasmonic, and multiferroic nanostructures. The implementation of multifunctional nanoscale devices rests upon our understanding of the structure-property and property-property correlations in nanomaterials. The project activities will explore complementary approaches to multifunctionality: internal (i.e. impurity-induced) and external (i.e. via heterostructure or composite formation).**

我的研究的主要目的是了解低维材料中不同性质共存和相互作用的基本原理，这些原理通常被认为是相互排斥的。同时控制和操纵纳米级的多个功能相关特性可能会导致富有富有效率的信息技术，固态照明，光子学和催化的新方法。该提案专门解决了多功能性对新的可持续技术的重要性，对加拿大具有长期利益。我的研究计划本质上是跨学科的，并结合了综合，光谱，结构，物理和理论方法。在设计项目中，我们研究了纳米结构大小，组成，相变，天然缺陷形成和分子功能化在增强纳米级固有自由度方面的作用。这些项目和与该提案相关的未来活动可以分为两个主要方向：*******节能固态照明和光子技术。扩大我在透明金属氧化物纳米晶体中功能缺陷形成和相互作用的工作，我的研究计划的这一部分的目的是探索扩展和操纵天然缺陷状态的电子结构和光学特性的不同方法。作为一个值得注意的例子，我们准备了一类新的胶体混合有机无机 - 有机式single白光发光纳米结构（纳米石），该纳米岩（纳米岩）为新的方法铺平了固态照明的方法，而无需进行战略上重要的稀土元件。 *******节能信息技术。这组项目的目的是研究纳米材料的电气，磁性和光学特性之间的相关性，以进行节能和非挥发性信息处理，传输和存储。感兴趣的系统包括磁性半导体，新兴的氧化氧化等离子和多性纳米结构。 多功能纳米级设备的实施取决于我们对纳米材料中结构质质和财产 - 特性相关性的理解。项目活动将探讨多功能性的互补方法：内部（即杂质引起的）和外部（即通过异质结构或复合形成）。**
