Abstract

Metal halide perovskite nanocrystals have attracted substantial interest given their easy manufacturing, superior Photoluminiscence Quantum Yield and striking optical properties. Despite the huge potential of such materials, their practical implementation and future technological applications need to overcome stability drawbacks: spontaneous degradation, which is accelerated by external stressors (i.e., moisture, oxygen, heat, light, and their combinations), poor phase stability and loss of their colloidal stability due to ligand lability. Within this framework, the understanding of their surface chemistry features and ligand-binding patterns plays a key role in improving the robustness and stability of perovskite nanocrystals. This review presents a comprehensive study of state-of-the-art and current challenges in surface chemistry, interface engineering and encapsulation methodologies for stabilizing lead halide perovskite nanoparticles. We first introduced lead halide perovskite structural and optical properties and a brief discussion of synthesis methods. Next, we explored recent developments in encapsulation methods in different protective matrices comprising from core-shell to macroscale nanocomposites. We also analyzed the advantages and shortcomings of each approach according to their final applications. Finally, we concluded with a discussion of open research challenges and future directions in the aforementioned aspects.

Quality index

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal Applied Materials Today due to its progression and the good impact it has achieved in recent years, according to the agency WoS (JCR), it has become a reference in its field. In the year of publication of the work, 2023, it was in position 85/439, thus managing to position itself as a Q1 (Primer Cuartil), in the category Materials Science, Multidisciplinary.

From a relative perspective, and based on the normalized impact indicator calculated from World Citations provided by WoS (ESI, Clarivate), it yields a value for the citation normalization relative to the expected citation rate of: 1.13. This indicates that, compared to works in the same discipline and in the same year of publication, it ranks as a work cited above average. (source consulted: ESI Nov 14, 2024)

This information is reinforced by other indicators of the same type, which, although dynamic over time and dependent on the set of average global citations at the time of their calculation, consistently position the work at some point among the top 50% most cited in its field:

  • Weighted Average of Normalized Impact by the Scopus agency: 1.36 (source consulted: FECYT Feb 2024)
  • Field Citation Ratio (FCR) from Dimensions: 2.63 (source consulted: Dimensions Jun 2025)

Specifically, and according to different indexing agencies, this work has accumulated citations as of 2025-06-26, the following number of citations:

  • WoS: 9
  • Scopus: 9
  • OpenCitations: 3

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-06-26:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 32.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 32 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 3.55.
  • The number of mentions on the social network X (formerly Twitter): 4 (Altmetric).

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:
