Purpose – This paper aims to explore the influence of career expectations on job satisfaction of Generation Y, as well as the mediating effect of career expectations on the relationship between hotel career management (HCM) and job satisfaction. Design/methodology/approach – Data were collected from the main tourist cities in China with Generation Y employees working in the hospitality industry as the target population. A total of 442 valid questionnaires were obtained, and structural equation modeling was used to examine the relationships among the constructs. Findings – HCM contributed positively to employees’ career expectation and job satisfaction. Career expectation was positively related to job satisfaction, as well as mediated the relationship between HCM and job satisfaction. Research limitations/implications – This study is limited by the use of self-reported data in the cross-sectional design because all participants filled out the questionnaires by themselves. The use of convenience sampling method presents another limitation for this study. Practical implications – This study may serve as a guide for managers and policymakers. First, this study highlights the importance of effective career management activities. Second, this study may help hotels retain the qualified staff members. Third, this study may help hotel managers respond to the career expectation of their young employees. Social implications – The meditating effect of career expectation highlights its importance in the career management system. The main force of market labor is Generation Y, who are known for their high career expectation and their emphasis on their career development. The findings indicate that both extrinsic and intrinsic value factors provide greater contributions to job satisfaction than prestige and stability factors. Therefore, hotels must provide a stable working environment, and care more on employees’ intrinsic value. Aside from providing high compensation, employers should also provide career growth opportunities and challenging job to their employees, as they are important motivational factors. By providing tailor-made career activities, hotel managers may satisfy the career expectations and enhance the job satisfaction of young employees, which, in turn, leads to a mutually beneficial situation for both managers and employees. Originality/value – This study explores the predictors and outcomes of career expectations of Generation Y employees. It highlights the importance of meeting the career expectations and also shows initial evidence on the mediating effect of career expectation. The findings of this study may provide useful guidance to both hotel operators and employees.

The metallic-structure dependent localized surface plasmons (LSPs) coupling behaviors with InGaN QWs in a green LED epitaxial wafer are investigated by optical transmission, scanning electron microscopy (SEM) and photoluminescence (PL) measurements. Ag nanoparticles (NPs) are formed by thermal annealing Ag layer on the green LED wafer. SEM images show that for higher annealing temperature and/or thicker deposited Ag layer, larger Ag NPs can be produced, leading to the redshift of absorption peaks in the transmission spectra. Time resolved PL (TRPL) measurements indicate when LSP-MQW coupling occurs, PL decay rate is greatly enhanced especially at the resonant wavelength 560 nm. However, the PL intensity is suppressed by 3.5 folds compared to the bare LED. The resonant absorption and PL suppression are simulated by three dimension finite-difference-time-domain (FDTD), which suggests that Ag particle with smaller size and lower height lead to the larger dissipation of LSP.

In this paper, we propose and demonstrate a convenient and flexible approach for preparation large-area of photonic crystals (PhCs) structures on the GaN-based LED chip. The highly-ordered porous anodic alumina (AAO) with pitch of wavelength scale was adopted as a selective dry etching mask for PhCs-pattern transfer. The PhCs with different pore depths were simultaneously formed on the entire surfaces of GaN-based LED chip including ITO, GaN surrounding contacts and the sidewall of the mesa by one-step reactive ion etching (RIE). The light output power improvement of PhCs-based GaN LED was achieved as high as 94% compared to that of the conventional GaN-based LED.
