How to publish in this journal

Scope

Leukos , the journal of the Illuminating Engineering Society (IES), is an international venue for technical developments, scientific discoveries, and experimental results of current interest or lasting importance in the applied use of light. Topics of interest include visual and non-visual responses to optical radiation, all aspects of the technologies employed in the generation, control, measurement, and computation of light and color, the lighting design of interior and exterior environments, and crosscutting topics that include daylighting, energy management, economics, and sustainability. Leukos publishes several types of manuscripts: 1. Scientific research results. Research results of significant and archival value in those scientific disciplines directly or indirectly related to light. 2. Engineering developments. Reports on new or improved equipment, materials, processes, or systems used directly or indirectly in lighting, lighting equipment, or lighting design. 3. Technical aspects of lighting applications. Technical aspects related to electric lighting, daylighting, lighting controls, standards and innovations in design. 4. Tutorial articles or critical reviews. Summaries of a technical topic in lighting of general interest, written specifically for study and instructional purposes. Tutorials and reviews are meant for technically knowledgeable readers who are not specialists in the subjects treated. 5. Brief communications. These are notes or short articles, of a technical nature that do not have the scope or extensive results of large studies or engineering projects, but provide useful data, analyses, or information.

Quartiles

The set of journals have been ranked according to their SJR and divided into four equal groups, four quartiles. Q1 (green) comprises the quarter of the journals with the highest values, Q2 (yellow) the second highest values, Q3 (orange) the third highest values and Q4 (red) the lowest values.

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

Cites per Doc

Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents.
